Properties
animationAnimation
Sets or gets the animation mode. Animation is disabled when the property is set to 'none'
Default valueadvanced
autoHideItemsany
A getter that returns an array of all DockingLayout items that are auto hidden inside the element.
Default value
autoLoadStateboolean
Enable/Disable the automatic state loading. There must be a previously saved state of the Layout in order to load it.
Default valuefalse

Enable/Disable the automatic state saving.
Note: In order to save the state of the element it must have an id.
Default valuefalse
disabledboolean

Default value
layoutany
Determines the structure of the element. This property represents an array of objects that define the hierarchy of the items inside the element and their specific settings. Each object must have a type attribute that defines it's behavior.
Three types of objects are allowed:
- LayoutGroup - Represents a group of items (Splitter). Used when the user wants more than one DockingLayout item in a single container.
Properties:- orientation - A string value indicating the orientation of the Splitter group. Possible values: 'horizontal', 'vertical'.
- size - A string | number value indicating the size of the Splitter group.
- items - An array of LayoutPanel object definitions.
- resizeMode - A string indicating the resize mode. Possible values: 'none', 'adjacent', 'end', 'proportional'.
- resizeStep - A nummeric value that determines the step of resizing.
- liveResize - Determines if splitter resizing happens while dragging or not.
- LayoutPanel - Represents a DockingLayout item (TabsWindow). LayoutPanels can have one or many items (TabItem).
Properties:- id - the ID of the LayoutPanel.
- autoHide - a boolean property that determines if the LayoutPanel is autoHidden.
- autoHidePosition - determines the autoHide position of the item if 'autoHide' property is set. Possible values: 'top', 'bottom', 'left', 'right'.

Possible values: 'top', 'bottom', 'left', 'right', 'center', 'header', 'layout-top', 'layout-bottom', 'layout-left', 'layout-right'. Positions with the 'layout' prefix reflect on LayoutPanelItems that are children of the LayoutPanel.
- label - the Label of the LayoutPanel window.
- tabPosition - Determines the position of the Tab labels inside the LayoutPanel.
- layout - determines the DockingLayout owner of the LayoutPanel. Accepts a string indicating the ID of a DockingLayout on the page or a direct reference to it.

- tabCloseButtons - a boolean property that Enables or disables the close buttons inside each Tab item label inside the DockingLayout item.
- tabOverflow - same as 'overflow' property of smartTabs. It defines the overflow mode of the labels of the Tab items inside a DockingLayout item.
- selectionMode - the same as smartTabs selection modes. Applies to Tab items inside a DockingLayout item.
- tabResize - the same as 'resize' property of smartTabs. Allows resizing the Tab labels inside the DockingLayout item.
- locked - Locks the size of the item and does not allow resizing.
- max - sets the maximum size of the item.
- min - sets the minimum size of the item
- size - sets the size of the item.
- items - an array of objects. Each object defines the structure of a LayoutPanelItem.
