This section explains briefly about how to create a Menu control in your application with JavaScript. The Essential JavaScript Menu supports displaying a Menu of list-out items. This Menu is based on ul-li hierarchy, where the sub-list items are rendered as the sub-menu items. The Menu control can also be rendered with local and remote data source. From the following guidelines, you can learn how to customize the Menu control for a website. In this case, Syncfusion’s website Menu is discussed. The following screenshot displays the appearance of Menu.

Create a Menu in React JS

Essential JavaScript Menu widgets are basically provided with built-in features like keyboard navigation, show and hide Menu items with animations, and flexible API’s. From the following guidelines, you can learn how to render Menu control with Remote data source value.

You can create a React application and add necessary scripts and styles with the help of the given React Getting Started Documentation.

Define an HTML element for adding Menu in the application and refer the JSX file.

  • html
  • <div id="menu-default"></div>
    <script src="app/menu/default.js">

    Create a JSX file for rendering Menu component using <EJ.Menu> syntax. Add required properties to it in <EJ.Menu> tag element

  • javascript
  • "use strict";
    
    ReactDOM.render(
        <div className="imgframe">
        <EJ.Menu width="100%">
        </EJ.Menu>
        </div>,
    document.getElementById('menu-default')
    );

    Output of the above steps.

    Configure parent Menu items

    Every Menu has a list of Menu items with list of sub level Menu items. From the following guidelines, you can learn how to initialize the root level elements of Menu control with Local data source value. Initialize the Menu with data source value as illustrated in the following code example.

  • html
  • <div id="menu-default"></div>
    <script src="app/menu/default.js">
  • javascript
  • "use strict";
    var data = [
                { id: 1, text: "Products", parentId: null },
                { id: 2, text: "Support", parentId: null },
                { id: 3, text: "Purchase", parentId: null },
                { id: 4, text: "Downloads", parentId: null },
    			{ id: 5, text: "Company", parentId: null }];
    ReactDOM.render(
        <div className="imgframe">
        <EJ.Menu fields-dataSource ={data} fields-id="id" fields-text="text" fields-parentid="parentId" width="500px">
        </EJ.Menu>
        </div>,
    document.getElementById('menu-default')
    );

    The following screenshot displays output.

    Initialize sub-level Menu items

    Every Menu items have a list of sub level Menu items. From the following guidelines, you can learn how to initialize the sub level items of Menu control. The parentId field is used to map root level Menu item to its sub level Menu item.

    The following code example describes how to initialize first level sub menu items of product Menu item.

  • javascript
  • "use strict";
    var data = [
                { id: 1, text: "Products", parentId: null },
                { id: 2, text: "Support", parentId: null },
                { id: 3, text: "Purchase", parentId: null },
                { id: 4, text: "Downloads", parentId: null },
    			{ id: 5, text: "Company", parentId: null },
                //first level child
                { id: 11, parentId: 1, text: "ASP.NET" },
                { id: 12, parentId: 1, text: "ASP.NET MVC" },
                { id: 13, parentId: 1, text: "Mobile MVC" },
                { id: 14, parentId: 1, text: "Silverlight" },
                { id: 15, parentId: 2, text: "Direct-Trac Support" },
                { id: 16, parentId: 2, text: "Community Forums" },
                { id: 17, parentId: 2, text: "Knowledge Base" },
                { id: 18, parentId: 2, text: "Services" },
    			{ id: 19, parentId: 4, text: "Evaluation" },
    			{ id: 20, parentId: 4, text: "Free E-Books" },
    			{ id: 21, parentId: 4, text: "Metro Studio" },
    			{ id: 22, parentId: 4, text: "Latest Version" },
    			{ id: 23, parentId: 5, text: "Technology Resource Portal " },
    			{ id: 24, parentId: 5, text: "Case Studies" },
    			{ id: 25, parentId: 5, text: "Bouchers & Datasheets" },
    			{ id: 26, parentId: 5, text: "FAQ" }                   
            ];
    ReactDOM.render(

     var data = [
                { id: 1, text: "Products", parentId: null },
                { id: 2, text: "Support", parentId: null },
                { id: 3, text: "Purchase", parentId: null },
                { id: 4, text: "Downloads", parentId: null },
    			{ id: 5, text: "Company", parentId: null },
                //first level child
                { id: 11, parentId: 1, text: "ASP.NET" },
                { id: 12, parentId: 1, text: "ASP.NET MVC" },
                { id: 13, parentId: 1, text: "Mobile MVC" },
                { id: 14, parentId: 1, text: "Silverlight" },
                { id: 15, parentId: 2, text: "Direct-Trac Support" },
                { id: 16, parentId: 2, text: "Community Forums" },
                { id: 17, parentId: 2, text: "Knowledge Base" },
                { id: 18, parentId: 2, text: "Services" },
    			{ id: 19, parentId: 4, text: "Evaluation" },
    			{ id: 20, parentId: 4, text: "Free E-Books" },
    			{ id: 21, parentId: 4, text: "Metro Studio" },
    			{ id: 22, parentId: 4, text: "Latest Version" },
    			{ id: 23, parentId: 5, text: "Technology Resource Portal " },
    			{ id: 24, parentId: 5, text: "Case Studies" },
    			{ id: 25, parentId: 5, text: "Bouchers & Datasheets" },
    			{ id: 26, parentId: 5, text: "FAQ" },
                //second level child
                {id: 111, parentId: 18, text: "Consulting" },
                { id: 112, parentId: 18, text: "Training" }            
            ];
    ReactDOM.render(
        <div className="imgframe">
        <EJ.Menu fields-dataSource ={data} width="100%">
        </EJ.Menu>
        </div>,
