Menu Javascript API

Class

Menu

Horizontal, Vertical and Popup Menu. Popup Menus appear when a user taps an interactive UI element such as an icon, button, action, or content, such as selected items or text.

Selector

smart-menu

Properties

Events

Methods

Properties

animation"none" | "simple" | "advanced"

Sets or retrieves the current animation mode. When this property is set to 'none', all animations are disabled and the element remains static. Otherwise, animations will be enabled according to the specified mode.

Allowed Values

• "none" - animation is disabled
• "simple" - ripple animation is disabled
• "advanced" - all animations are enabled

 <smart-menu animation='none'></smart-menu>

 const menu = document.querySelector('smart-menu');

 menu.animation = 'simple';

 const menu = document.querySelector('smart-menu');

 let animation = menu.animation;

autoCloseDelaynumber

Specifies the delay, in milliseconds, before the Menu dropdown is closed after the mouse cursor leaves the Menu area. This setting is only effective when the selectionMode property is set to 'mouseenter'. Adjusting this value can help prevent the dropdown from closing too quickly when the mouse briefly leaves the Menu.

 <smart-menu auto-close-delay='1000'></smart-menu>

 const menu = document.querySelector('smart-menu');

 menu.autoCloseDelay = 200;

 const menu = document.querySelector('smart-menu');

 let autoCloseDelay = menu.autoCloseDelay;

autoFocusOnMouseenterboolean

If set to true, the element will automatically receive focus when the user's mouse pointer enters (hovers over) it, triggering a mouseenter event. This allows keyboard interactions or focus styles to activate without requiring a manual click or tab action from the user.

 <smart-menu auto-focus-on-mouseenter></smart-menu>

 const menu = document.querySelector('smart-menu');

 menu.autoFocusOnMouseenter = false;

 const menu = document.querySelector('smart-menu');

 let autoFocusOnMouseenter = menu.autoFocusOnMouseenter;

checkableboolean

Enables checkboxes for top-level menu items (the direct children of the main Menu component), allowing users to select or deselect these items. To make submenu items (nested within menu groups) checkable, set the checkable property individually on the corresponding smart-menu-items-group elements. This allows for granular control over which menu levels support checkable states.

 <smart-menu checkable></smart-menu>

 const menu = document.querySelector('smart-menu');

 menu.checkable = false;

 const menu = document.querySelector('smart-menu');

 let checkable = menu.checkable;

checkboxesboolean

Controls whether checkboxes and radio buttons can be shown within the Menu component. This property applies exclusively to the main Menu, not to its subitems (i.e., smart-menu-item or smart-menu-items-group). Use this property to enable or disable the display of selectable options directly in the Menu.
For further customization of individual items, refer to the checkable property.

 <smart-menu checkboxes></smart-menu>

 const menu = document.querySelector('smart-menu');

 menu.checkboxes = false;

 const menu = document.querySelector('smart-menu');

 let checkboxes = menu.checkboxes;

checkMode"checkbox" | "radioButton"

Sets the selection mode (check mode) for the top-level Menu items, which are the immediate children of the Menu component. The 'checkMode' property determines how these menu items can be toggled or selected:

- Possible values for 'checkMode' are:
- ''checkbox'': Menu items can be checked and unchecked independently (multiple selections allowed).
- ''radioButton'': Menu items are mutually exclusive (only one can be selected at a time, like radio buttons).
- ''none'': Menu items have no checkable or selectable state.

You can also assign a comma-separated list of these values (for example, ''checkbox, radioButton, none, checkbox''). If a list is provided, each value corresponds to a group of top-level menu items. These groups are separated by menu separators (special items acting as visual dividers). The first value in the list applies to the first group of menu items, the second value to the next group (after the first separator), and so on. When a separator is encountered, it signals the start of a new checkMode context, applying the next value in the list to subsequent items.

Note: This 'checkMode' property only affects the top-level menu items. To control check modes for submenus or nested groups, set the 'checkMode' property individually on each smart-menu-items-group (the group component representing submenu levels).

Allowed Values

• "checkbox" - A check box is shown inside a menu item that is selected.
• "radioButton" - A radio dot is shown inside a menu item that is selected.

 <smart-menu check-mode='radioButton'></smart-menu>

 const menu = document.querySelector('smart-menu');

 menu.checkMode = 'checkbox';

 const menu = document.querySelector('smart-menu');

 let checkMode = menu.checkMode;

closeAction"down" | "up" | "none"

Defines the document-level event that triggers the closure of all open menu dropdowns, or the entire menu if the mode property is set to 'dropDown'. This event ensures that any active menu or submenu is properly closed when the specified user interaction occurs (e.g., clicking outside the menu).

Allowed Values

• "down" - Closes the drop down on document down event.
• "up" - Closes the drop down on document up event.
• "none" - The drop down can be closed only from the menu.

 <smart-menu close-action='down'></smart-menu>

 const menu = document.querySelector('smart-menu');

 menu.closeAction = 'none';

 const menu = document.querySelector('smart-menu');

 let closeAction = menu.closeAction;

dataSource{label: string, shortcut: string, value: any, items:[]}[]

Specifies the data source for the Menu component. The data source should be provided as an array of objects, where each object represents a menu item with the following properties:

- 'label': *(string, required)* — The text displayed for the menu item.
- 'value': *(any, required)* — The unique value associated with the menu item, used for identification or selection.
- 'shortcut': *(string, optional)* — A keyboard shortcut hint displayed alongside the menu item, helping users discover quick access keys.
- 'items': *(array, optional)* — An array of objects representing sub-menu items, allowing for nested menus and hierarchical structures. Each sub-menu item follows the same structure as a top-level menu item.

By configuring the data source in this format, you enable dynamic and flexible rendering of complex menu structures.

 <smart-menu data-source='[{ label: "File" }, { label: "Help" }]'></smart-menu>

 const menu = document.querySelector('smart-menu');

 menu.dataSource = [{ label: 'File', items: [{ label: 'New', shortcut: 'Ctrl+N' }] }];

 const menu = document.querySelector('smart-menu');

 let dataSource = menu.dataSource;

disabledboolean

Controls whether the element is active and interactive (enabled) or inactive and non-interactive (disabled). When disabled, users cannot interact with the element.

 <smart-menu disabled></smart-menu>

 const menu = document.querySelector('smart-menu');

 menu.disabled = false;

 const menu = document.querySelector('smart-menu');

 let disabled = menu.disabled;

displayMemberstring

Specifies which field in the data source should be used as the item's label. This determines the text value displayed for each item in the UI by mapping it to the corresponding property from your data.

 <smart-menu display-member='title'></smart-menu>

 const menu = document.querySelector('smart-menu');

 menu.displayMember = 'caption';

 const menu = document.querySelector('smart-menu');

 let displayMember = menu.displayMember;

dropDownAppendTostring | HTMLElement

Here is a revised and enhanced version of your description:

Specifies a custom outer container to which all dropdown containers will be appended. By default, dropdown elements are appended inside the menu itself. You can assign this property an HTML element directly, or provide the id of an existing HTML element (as a string).

When the menu is in mode 'dropDown', the dropDownAppendTo property not only determines where the dropdowns are appended, but also controls the parent container of the entire menu. Note that the open method will open the menu relative to its original position within the DOM, regardless of the value of dropDownAppendTo.

Use this property to customize the DOM structure, for example, to ensure that dropdowns are rendered within a specific container for layout, styling, or layering purposes.

 <smart-menu drop-down-append-to='body'></smart-menu>

 const menu = document.querySelector('smart-menu');

 menu.dropDownAppendTo = 'customContainer';

 const menu = document.querySelector('smart-menu');

 let dropDownAppendTo = menu.dropDownAppendTo;

dropDownOverlayboolean

When this property is enabled, opening an element’s dropdown will display a transparent overlay that covers the area between the dropdown and the rest of the page. This overlay prevents interaction with other page elements while the dropdown is open, helping to focus the user’s attention on the dropdown content.

 <smart-menu drop-down-overlay></smart-menu>

 const menu = document.querySelector('smart-menu');

 menu.dropDownOverlay = false;

 const menu = document.querySelector('smart-menu');

 let dropDownOverlay = menu.dropDownOverlay;

dropDownPosition"auto" | "top-left" | "top-right" | "bottom-left" | "bottom-right" | "overlay-left" | "overlay-right"

Specifies the direction in which the menu dropdown will appear when opened (e.g., above, below, left, or right relative to the triggering element), allowing customization of dropdown placement to enhance user interface layout and usability.

Allowed Values

• "auto" - The position is automatically determined by measuring the available distance around the element for the drop down to open freely without being clipped by the edges of the browser. By default the drop down will try to open below the element. If the available space is not enough for the popup to appear it will open in one of the following directions, if possible: top, over.
• "top-left" - The drop down opens above and to the left of the seleted Item Group.
• "top-right" - The drop down opens above and to the right of the seleted Item Group.
• "bottom-left" - The drop down opens below and to the left of the seleted Item Group.
• "bottom-right" - The drop down opens below and to the right of the seleted Item Group.
• "overlay-left" - The drop down opens over the seleted Item Group by aligning to the left.
• "overlay-right" - The drop down opens over and to the left of the seleted Item Group by aligning to the right.

 <smart-menu drop-down-position='top-left'></smart-menu>

 const menu = document.querySelector('smart-menu');

 menu.dropDownPosition = 'top-right';

 const menu = document.querySelector('smart-menu');

 let dropDownPosition = menu.dropDownPosition;

itemsarray

A getter method that retrieves and returns an array containing all current Menu item objects, allowing access to the complete list of menu entries managed by the application.

itemsMemberstring

Specifies the field name in the data source that contains the collection of subitems associated with each item group. This property allows the component to identify and retrieve subitems for each group by referencing the appropriate data field.

 <smart-menu items-member='children'></smart-menu>

 const menu = document.querySelector('smart-menu');

 menu.itemsMember = 'subitems';

 const menu = document.querySelector('smart-menu');

 let itemsMember = menu.itemsMember;

unlockKeystring

Retrieves or assigns the unlockKey, a unique code required to activate and access the product's full features.

 <smart-menu unlock-key=''></smart-menu>

 const menu = document.querySelector('smart-menu');

 menu.unlockKey = '1111-2222-3333-4444-5555';

 const menu = document.querySelector('smart-menu');

 let unlockKey = menu.unlockKey;

localestring

Specifies or retrieves the current language setting for the component. This property determines which language is used when displaying text from the messages property, allowing for dynamic localization and internationalization of the user interface. When the language is changed, the corresponding localized messages are retrieved from the messages object.

 <smart-menu locale='de'></smart-menu>

 const menu = document.querySelector('smart-menu');

 menu.locale = 'en';

 const menu = document.querySelector('smart-menu');

 let locale = menu.locale;

localizeFormatFunctionfunction | null

A callback function that allows you to customize the formatting of messages returned by the Localization Module. Use this to modify how localized strings are generated or displayed, such as adjusting placeholders, applying additional formatting, or handling special localization rules before the message is returned.

 <smart-menu localize-format-function='function(defaultMessage, message, messageArguments){return '...'}'></smart-menu>

 const menu = document.querySelector('smart-menu');

 menu.localizeFormatFunction = function(defaultMessage, message, messageArguments){return '...'};

 const menu = document.querySelector('smart-menu');

 let localizeFormatFunction = menu.localizeFormatFunction;

messagesobject

Specifies or retrieves an object containing the set of strings used within the widget interface that can be localized for different languages. This property works together with the locale property to enable internationalization by allowing developers to customize or translate UI text according to the user's language preferences.

 <smart-menu messages='{"de":{"propertyUnknownType":"'{{name}}' Eigenschaft ist mit undefined 'Typ'-Member!","propertyInvalidValue":"Invalid '{{name}}' property value! Actual value: {{actualValue}}, Expected value: {{value}}!","propertyInvalidValueType":"Invalid '{{name}}' property value type!

 const menu = document.querySelector('smart-menu');

 menu.minimizeIconTemplate = 'template2';

 const menu = document.querySelector('smart-menu');

 let minimizeIconTemplate = menu.minimizeIconTemplate;

minimizeWidthnumber

Specifies the minimum width (in pixels) at which the Menu transitions from its normal (expanded) state to a minimized (collapsed) mode. When the Menu’s container width falls below this threshold, the minimized mode is automatically activated. If set to null, the Menu will remain in its normal state regardless of width and will not minimize automatically.

 <smart-menu minimize-width='100'></smart-menu>

 const menu = document.querySelector('smart-menu');

 menu.minimizeWidth = 200;

 const menu = document.querySelector('smart-menu');

 let minimizeWidth = menu.minimizeWidth;

mode"horizontal" | "vertical" | "dropDown" | "tree"

 let opened = menu.opened;

overflow"auto" | "hidden" | "scroll"

Defines how the menu's scroll buttons behave when navigating through its items. This property is effective only if dropDownAppendTo is set to a value other than null. If dropDownAppendTo is null, the scroll button behavior setting is ignored.

Allowed Values

• "auto" - The scroll buttons are automatically shown/hidden depending on the visibility of the items. If there's an item that is not visible the appropriate scroll button will appear in order to fully scroll to it.
• "hidden" - The scroll buttons are hidden.
• "scroll" - The scroll buttons are always visible.

 <smart-menu overflow='hidden'></smart-menu>

 menu.overflow = 'scroll';

 const menu = document.querySelector('smart-menu');

 let overflow = menu.overflow;

preventCloseOnCheckboolean

If set to true, the Menu and its dropdowns will remain open when a Menu item is checked or unchecked, rather than automatically closing upon selection. This allows users to make multiple selections without the Menu closing each time an item is toggled.

 <smart-menu prevent-close-on-check></smart-menu>

 const menu = document.querySelector('smart-menu');

 menu.preventCloseOnCheck = false;

 const menu = document.querySelector('smart-menu');

 let preventCloseOnCheck = menu.preventCloseOnCheck;

readonlyboolean

When the element is set to "readonly," users can view its content but are unable to modify or edit the value. However, users may still interact with the element in limited ways, such as selecting and copying its content. The element remains focusable, but any attempts to change its data will be ignored.

 <smart-menu readonly></smart-menu>

 const menu = document.querySelector('smart-menu');

 menu.readonly = true;

 const menu = document.querySelector('smart-menu');

 let readonly = menu.readonly;

rightToLeftboolean

Specifies or retrieves whether the element’s alignment is configured to support locales that use right-to-left (RTL) text direction, such as Arabic or Hebrew. When enabled, the element’s content and layout are adjusted for proper display in RTL languages.

 <smart-menu right-to-left></smart-menu>

 <smart-menu unfocusable></smart-menu>

 const menu = document.querySelector('smart-menu');

 menu.unfocusable = false;

 const menu = document.querySelector('smart-menu');

 let unfocusable = menu.unfocusable;

valueMemberstring

Specifies which field in the data source should be used as the value for each item. This property maps a particular key or column from your data to represent the item's value in the component, enabling proper identification, selection, and data binding.

 <smart-menu value-member='info'></smart-menu>

 const menu = document.querySelector('smart-menu');

 menu.valueMember = 'details';

 const menu = document.querySelector('smart-menu');

 let valueMember = menu.valueMember;
