Hierarchy

The Kendo UI Drawer provides the built-in functionality to create a hierarchical structure. Visit the Hierarchy demo for a live example.

Configuration

To utilize the hierarchy functionality of the Kendo UI Drawer:

  1. Add list elements with data-role attribute drawer-item and class hidden to the drawer template.

    $("#drawer").kendoDrawer({
    template: "<ul> \
                <li data-role='drawer-item' class='k-state-selected'><span class='k-icon k-i-information'></span><span class='k-item-text' data-id='GettingStarted'>Getting Started</span><span class='k-spacer'></span><span class='k-icon k-i-arrow-chevron-right'></span></li> \
                <li data-role='drawer-separator'></li> \
                <li data-role='drawer-item' class='hidden'><span class='k-icon k-i-none'></span><span class='k-icon k-i-question'></span><span class='k-item-text' data-id='Kendo'>About Kendo UI</span></li> \
                <li data-role='drawer-item' class='hidden'><span class='k-icon k-i-none'></span><span class='k-icon k-i-palette'></span><span class='k-item-text' data-id='ThemeSupport'>Supported Themes</span></li> \
                <li data-role='drawer-separator'></li> \
                <li data-role='drawer-item'><span class='k-icon k-i-zoom'></span><span class='k-item-text' data-id='Overview'>Overview</span><span class='k-spacer'></span><span class='k-icon k-i-arrow-chevron-right'></li> \
                <li data-role='drawer-item' class='hidden'><span class='k-icon k-i-none'></span><span class='k-icon k-i-js'></span><span class='k-item-text' data-id='About'>About Kendo</span></li> \
                <li data-role='drawer-item' class='hidden'><span class='k-icon k-i-none'></span><span class='k-icon k-i-style-builder'></span><span class='k-item-text' data-id='All'>All Kendo Components</span></li> \
                <li data-role='drawer-separator'></li> \
                <li data-role='drawer-item'><span class='k-icon k-i-star'></span><span class='k-item-text' data-id='Popular'>Most popular components</span></li> \
              </ul>"
    });
    
  2. In the itemClick event of the drawer handle the expansion and collapse of the hierarchical items.

    $("#drawer").kendoDrawer({
        itemClick: function (e) {
            if (!e.item.hasClass("k-drawer-separator")) {
                var drawerContainer = e.sender.drawerContainer;
                var expandIcon = e.item.find("span.k-i-arrow-chevron-right");
                var collapseIcon = e.item.find("span.k-i-arrow-chevron-down");
                drawerContainer.find("#drawer-content > div").addClass("hidden");
                drawerContainer.find("#drawer-content").find("#" + e.item.find(".k-item-text").attr("data-id")).removeClass("hidden");
    
                /* If the expandIcon is visible, the sub-items are hidden. Clicking on the icon should remove the hidden class and reveal the items.*/
                if (expandIcon.length) {
                    e.item.nextAll(".k-drawer-item:not(.k-drawer-separator):lt(2)").removeClass("hidden");
                    expandIcon.removeClass("k-i-arrow-chevron-right").addClass("k-i-arrow-chevron-down");
                }
    
                /* If the collapseIcon is visible, the sub-items are visible. Clicking on the icon should add the hidden class and hide the items. */
                if (collapseIcon.length) {
                    e.item.nextAll(".k-drawer-item:not(.k-drawer-separator):lt(2)").addClass("hidden");
                    collapseIcon.addClass("k-i-arrow-chevron-right").removeClass("k-i-arrow-chevron-down");
                }
            }
        }
    });
