Overview

Smart.ListMenu represents a custom element which can be used to choose an option from a nested list of items. Navigation through the nested list is done in a single view.

Getting Started with ListMenu Web Component

Smart UI for Web Components is distributed as smart-webcomponents NPM package. You can also get the full download from our website with all demos from the Download page.

Setup the ListMenu

Smart UI for Web Components is distributed as smart-webcomponents NPM package

  1. Download and install the package.

    npm install smart-webcomponents

  2. Once installed, import the ListMenu module in your application.

    <script type="module" src="node_modules/smart-webcomponents/source/modules/smart.listmenu.js"></script>

  3. Adding CSS reference

    The smart.default.css CSS file should be referenced using following code.

    <link rel="stylesheet" type="text/css" href="node_modules/smart-webcomponents/source/styles/smart.default.css" />

  4. Add the ListMenu tag to your Web Page

    <smart-list-menu id="listmenu"></smart-list-menu>

  5. Create the ListMenu Component

    	<script type="module">
    		Smart('#listmenu', class {
    			get properties() {
    				return {checkboxes: true, checkable: true}
    			}
    		});
    	</script>	   
    		

    Another option is to create the ListMenu is by using the traditional Javascript way:
    	const listmenu = document.createElement('smart-list-menu');
    
    	listmenu.disabled = true;
    	document.body.appendChild(listmenu);
    		

    Smart framework provides a way to dynamically create a web component on demand from a DIV tag which is used as a host. The following imports the web component's module and creates it on demand, when the document is ready. The #listmenu is the ID of a DIV tag.

    	import "../../source/modules/smart.listmenu.js";
    
    	document.readyState === 'complete' ? init() : window.onload = init;
    
    	function init() { 
    		const listmenu = new Smart.ListMenu('#listmenu', {checkboxes: true, checkable: true});
    	}
    	

  6. Open the page in your web server.

Appearance

The list menu structure contains smart-menu-item and smart-menu-items-group elements.

The following attributes are available for these custom elements.

  • label - the label to be displayed in the list menu
  • separator - if present, a visual separator (horizontal line) is added after the item
  • disabled - disables the selection of an item

The following attributes are only available for smart-menu-item.

  • value - a custom value that is not displayed, but is passed as an argument to the itemClick event (called when an item is chosen).
  • shortcut - a helper text/icon that can represent a keyboard shortcut that activates the item. The shortcut is not displayed for top-level items in horizontal and vertical modes.

Animated list menu could be achieved when animation class is added .

 <smart-list-menu class="animation"></smart-list-menu>

Demo

The list menu and its items can have checkbox or radio button selection. To allow this the user has to set element's checkboxes property to true and checkable for the particular items or group.

 <smart-list-menu checkboxes checkable></smart-list-menu>

Demo

Data Binding

To initialize a populated Smart.ListMenu custom element, insert the required inner structure consisting of the auxiliary custom elements smart-menu-item and smart-menu-items-group, e.g.:

Behavior

Smart.ListMenu could be minimized/maximized. The element has minimizeWidth property. It determines the minimum width of the ListMenu at which it will switch from normal to minimized mode. If set to null, the ListMenu does not minimize automatically.

<!DOCTYPE html>
<html lang="en">
<head>
 <link rel="stylesheet" href="../../source/styles/smart.default.css" type="text/css" />
 <script type="text/javascript" src="../../source/smart.element.js"></script>
 <script type="text/javascript" src="../../source/smart.button.js"></script>
 <script type="text/javascript" src="../../source/smart.menu.js"></script>
 <script>
 window.onload = function () {
     document.querySelector('smart-list-menu').minimizeWidth = 1000;
 }
 </script>
</head>
<body>
    <smart-list-menu></smart-list-menu>
</body>
</html>

User can switch between few drop down positions. The value of dropDownPosition could be:

  • top-left
  • top-right
  • bottom-left
  • bottom-right
  • auto

The element supports filtering and grouping. The following filter modes are allowed:

  • contains
  • containsIgnoreCase
  • doesNotContain
  • doesNotContainIgnoreCase
  • equals
  • equalsIgnoreCase
  • startsWith
  • startsWithIgnoreCase
  • endsWith
  • endsWithIgnoreCase
<smart-list-menu filterable filter-mode="startsWith" filter-mode grouped></smart-list-menu>

             listMenu.setFocusable(false);
         }
     </script>
    
  • uncheckItem - unchecks an item. The id or the path to the item is passed in as the method argument.
     <script>
         window.onload = function () {
             var listMenu = document.querySelector('smart-list-menu');
             listMenu.uncheckItem('0.0');

Keyboard Support

Key Action
Tab The list menu receives focus by tabbing into it.
Arrow Up / Arrow Down Navigates to the previous/next item in the current view.
Arrow Left / Arrow Right Navigates to the previous/next view.
Home Navigates to the "back" button or the first enabled item (for the top-level view).
End Navigates to the last enabled item in the current view.
Enter Selects an item/opens an items group (new view). If the list menu is minimized and the minimized pop-up is closed, opens the pop-up.
Escape Navigates to the previous view. If the top-level view is reached and the list menu is minimized, closes the minimized pop-up.
Space Toggles an item's checked state.

Create, Append, Remove, Get/Set Property, Invoke Method, Bind to Event


Create a new element:
	const listmenu = document.createElement('smart-list-menu');
	

Append it to the DOM:
	document.body.appendChild(listmenu);
	

Remove it from the DOM:
	listmenu.parentNode.removeChild(listmenu);
	

Set a property:
	listmenu.propertyName = propertyValue;
	

Get a property value:
	const propertyValue = listmenu.propertyName;
	

Invoke a method:
	listmenu.methodName(argument1, argument2);
	

Add Event Listener:
	const eventHandler = (event) => {
	   // your code here.
	};

	listmenu.addEventListener(eventName, eventHandler);
	

Remove Event Listener:
	listmenu.removeEventListener(eventName, eventHandler, true);
	

Using with Typescript

Smart Web Components package includes TypeScript definitions which enables strongly-typed access to the Smart UI Components and their configuration.

Inside the download package, the typescript directory contains .d.ts file for each web component and a smart.elements.d.ts typescript definitions file for all web components. Copy the typescript definitions file to your project and in your TypeScript file add a reference to smart.elements.d.ts

Getting Started with Angular ListMenu Component

Setup Angular Environment

Angular provides the easiest way to set angular CLI projects using Angular CLI tool.

Install the CLI application globally to your machine.

npm install -g @angular/cli

Create a new Application

ng new smart-angular-listmenu

Navigate to the created project folder

cd smart-angular-listmenu

Setup the ListMenu

Smart UI for Angular is distributed as smart-webcomponents-angular NPM package

  1. Download and install the package.
    npm install smart-webcomponents-angular
  2. Once installed, import the ListMenuModule in your application root or feature module.

    app.module.ts

    import { NgModule } from '@angular/core';
    import { BrowserModule } from '@angular/platform-browser';
    
    import { ListMenuModule } from 'smart-webcomponents-angular/listmenu';
    
    import { AppComponent } from './app.component';
    
    @NgModule({
        declarations: [ AppComponent ],
        imports: [ BrowserModule, ListMenuModule ],
        bootstrap: [ AppComponent ],
    	entryComponents: [ AppComponent ]
    })
    
    export class AppModule { }
    	

  3. Adding CSS reference

    The following CSS file is available in ../node_modules/smart-webcomponents-angular/ package folder. This can be referenced in [src/styles.css] using following code.

    	@import 'smart-webcomponents-angular/source/styles/smart.default.css';

    Another way to achieve the same is to edit the angular.json file and in the styles add the style.

    	"styles": [
    		"node_modules/smart-webcomponents-angular/source/styles/smart.default.css"
    	]
    	
  4. Example


    app.component.html

     
    <smart-list-menu #listmenu id="listMenu" class="animation">

Getting Started with React ListMenu Component

Setup React Environment

The easiest way to start with React is to use create-react-app. To scaffold your project structure, follow the installation instructions.

	npm install -g create-react-app
	create-react-app my-app
	cd my-app
	npm start
	

Preparation

Open src/App.js andsrc/App.css

  1. Remove everything inside the App div tag in src/App.js:
    <div className="App"> </div>
  2. Remove the logo.svg import
  3. Remove the contents of src/App.css
  4. Remove src/logo.svg

Setup the ListMenu

Smart UI for React is distributed as smart-webcomponents-react NPM package

  1. Download and install the package.
    npm install smart-webcomponents-react
  2. Once installed, import the React ListMenu Component and CSS files in your application and render it app.js

    import 'smart-webcomponents-react/source/styles/smart.default.css';
    import React from "react";
    import ReactDOM from "react-dom";
    import { ListMenu, MenuItem, MenuItemsGroup } from 'smart-webcomponents-react/listmenu';
    
    class App extends React.Component {
    
    	init() {
    
    	}
    
    
    	componentDidMount() {
    
    	}
    
    	render() {
    		return (
    			<div>
    				<ListMenu id="listMenu" class="animation">
    					<MenuItemsGroup>File
    			            <MenuItem shortcut="Ctrl+N">New</MenuItem>

    							<MenuItemsGroup>Western European
    			                    <MenuItem>ISO 8859-1</MenuItem>
    								<MenuItem>ISO 8859-15</MenuItem>
    								<MenuItem>OEM 850</MenuItem>
    								<MenuItem>Windows-1252</MenuItem>
    							</MenuItemsGroup>
    						</MenuItemsGroup>
    						<MenuItem>Convert to ANSI</MenuItem>
    						<MenuItem>Convert to UTF-8</MenuItem>
    						<MenuItem>Convert to UTF-8-BOM</MenuItem>
    						<MenuItem>Convert to UTCS-2 BE BOM</MenuItem>
    						<MenuItem>Convert to UTCS-2 LE BOM</MenuItem>
    					</MenuItemsGroup>
    				</ListMenu>
    			</div>
    		);
    	}
    }
    
    ReactDOM.render(<App />, document.querySelector("#root"));
    
    export default App;
    	

Running the React application

Start the app with
npm start
and open localhost:3000 in your favorite web browser to see the output.

Getting Started with Vue ListMenu Component


Setup Vue Environment

We will use vue-cli to get started. Let's install vue-cli

npm install -g @vue/cli

Then we can start creating our Vue.js projects with:

vue create my-project

Setup the ListMenu

Open the "my-project" folder and run:

npm install smart-webcomponents

Setup with Vue 3.x

  • Make Vue ignore custom elements defined outside of Vue (e.g., using the Web Components APIs). Otherwise, it will throw a warning about an Unknown custom element, assuming that you forgot to register a global component or misspelled a component name.

    Open src/main.js in your favorite text editor and change its contents to the following:

    main.js

    import { createApp } from 'vue'
    import App from './App.vue'
    
    const app = createApp(App)
    
    app.config.isCustomElement = tag => tag.startsWith('smart-');
    app.mount('#app')
    		
  • Open src/App.vue in your favorite text editor and change its contents to the following:

    App.vue

    <template>
      <div class="vue-root">
        <smart-list-menu id="listMenu" class="animation">
          <smart-menu-items-group>

            <smart-menu-item shortcut="Ctrl+N">New</smart-menu-item>
            <smart-menu-item shortcut="Ctrl+0">Open</smart-menu-item>
            <smart-menu-items-group>

    export default {
      name: "app",

        onMounted(() => {});
      }
    };
    </script>
    
    <style>

    We can now use the smart-list-menu with Vue. Data binding and event handlers will just work right out of the box.
    We have bound the properties of the smart-list-menu to values in our Vue component.
