29 Nov 202312 minutes to read
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
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.
Create an HTML file and add the following template into it for Menu creation.
<!DOCTYPE html>
<html>
<head>
<meta name="viewport" content="width=device-width, initial-scale=1.0" charset="utf-8" />
<!-- Style sheet for default theme (flat azure) -->
<link href="http://cdn.syncfusion.com/24.2.3/js/web/flat-azure/ej.web.all.min.css" rel="stylesheet" />
<!--Scripts-->
<script src="http://cdn.syncfusion.com/js/assets/external/jquery-2.1.4.min.js"></script>
<script src="http://cdn.syncfusion.com/js/assets/external/jquery.easing.1.3.min.js"> </script>
<script src="http://cdn.syncfusion.com/24.2.3/js/web/ej.web.all.min.js"></script>
<!--Add custom scripts here -->
</head>
<body>
<!-- add menu element here -->
</body>
</html>Adding Ul element for Menu rendering.
<ul id="syncfusionProducts"></ul>Initialize the Menu control in <script> tag.
$(function () {
// document ready
// simple Menu control creation
$("#syncfusionProducts").ejMenu();
});Output of the above steps.
Configure parent Menu items
Every Menu has a list of Menu items with list of sub level Menu items. From the following guidelines, you can learn how to initialize the root level elements of Menu control with Local data source value. Initialize the Menu with data source value using fields property as illustrated in the following code example.
var data = [
{ id: 1, text: "Products", parentId: null },
{ id: 2, text: "Support", parentId: null },
{ id: 3, text: "Purchase", parentId: null },
{ id: 4, text: "Downloads", parentId: null },
{ id: 5, text: "Company", parentId: null }
];
jQuery(function ($) {
$("#syncfusionProducts").ejMenu({
fields: { dataSource: data, id: "id", parentId: "parentId", text: "text" }
});
});The following screenshot displays output.
Initialize sub-level Menu items
Every Menu items have a list of sub level Menu items. From the following guidelines, you can learn how to initialize the sub level items of Menu control. The parentId field is used to map root level Menu item to its sub level Menu item.
The following code example describes how to initialize first level sub menu items of product Menu item.
var data = [
{ id: 1, text: "Products", parentId: null },
{ id: 2, text: "Support", parentId: null },
{ id: 3, text: "Purchase", parentId: null },
{ id: 4, text: "Downloads", parentId: null },
{ id: 5, text: "Company", parentId: null },
//first level child
{ id: 11, parentId: 1, text: "ASP.NET" },
{ id: 12, parentId: 1, text: "ASP.NET MVC" },
{ id: 13, parentId: 1, text: "Mobile MVC" },
{ id: 14, parentId: 1, text: "Silverlight" },
{ id: 15, parentId: 2, text: "Direct-Trac Support" },
{ id: 16, parentId: 2, text: "Community Forums" },
{ id: 17, parentId: 2, text: "Knowledge Base" },
{ id: 18, parentId: 2, text: "Services" },
{ id: 19, parentId: 4, text: "Evaluation" },
{ id: 20, parentId: 4, text: "Free E-Books" },
{ id: 21, parentId: 4, text: "Metro Studio" },
{ id: 22, parentId: 4, text: "Latest Version" },
{ id: 23, parentId: 5, text: "Technology Resource Portal " },
{ id: 24, parentId: 5, text: "Case Studies" },
{ id: 25, parentId: 5, text: "Boucher's & Data sheets" },
{ id: 26, parentId: 5, text: "FAQ" }
];
jQuery(function ($) {
$("#syncfusionProducts").ejMenu({
fields: { dataSource: data, id: "id", parentId: "parentId", text: "text" }
});
});Execute the above code example to render the following output.
Define multiple level Menu items
You can define the sub-menu items to multiple levels in Menu control. You need to specify the parent Id value to render sub level Menu item for the Menu items.
To initialize multiple levels sub menu items, use the following code example.
var data = [
{ id: 1, text: "Products", parentId: null },
{ id: 2, text: "Support", parentId: null },
{ id: 3, text: "Purchase", parentId: null },
{ id: 4, text: "Downloads", parentId: null },
{ id: 5, text: "Company", parentId: null },
//first level child
{ id: 11, parentId: 1, text: "ASP.NET" },
{ id: 12, parentId: 1, text: "ASP.NET MVC" },
{ id: 13, parentId: 1, text: "Mobile MVC" },
{ id: 14, parentId: 1, text: "Silverlight" },
{ id: 15, parentId: 2, text: "Direct-Trac Support" },
{ id: 16, parentId: 2, text: "Community Forums" },
{ id: 17, parentId: 2, text: "Knowledge Base" },
{ id: 18, parentId: 2, text: "Services" },
{ id: 19, parentId: 4, text: "Evaluation" },
{ id: 20, parentId: 4, text: "Free E-Books" },
{ id: 21, parentId: 4, text: "Metro Studio" },
{ id: 22, parentId: 4, text: "Latest Version" },
{ id: 23, parentId: 5, text: "Technology Resource Portal " },
{ id: 24, parentId: 5, text: "Case Studies" },
{ id: 25, parentId: 5, text: "Boucher's & Data sheets" },
{ id: 26, parentId: 5, text: "FAQ" },
//second level child
{id: 111, parentId: 18, text: "Consulting" },
{ id: 112, parentId: 18, text: "Training" }
];
jQuery(function ($) {
$("#syncfusionProducts").ejMenu({
