Basic Widgets

Tabs

Tabs allow you to divide content into separate sections that can be toggled by clicking on the tab headers.

Example

<div class="easyui-tabs" style="width:500px;height:250px;">
    <div title="Tab1" style="padding:20px;">Content for Tab1</div>
    <div title="Tab2" style="padding:20px;">Content for Tab2</div>
</div>

Panels

Panels are used to group related content together and can be expanded or collapsed.

Example

<div class="easyui-panel" title="Panel Title" style="width:500px;height:250px;">
    <p>Panel content goes here.</p>
</div>

Advanced Widgets

Menus

Menus provide a way to display a list of options that can be clicked on to perform actions.

Example

<ul class="easyui-menu" style="width:150px;">
    <li><a href="#" data-options="iconCls:'icon-ok'">Option 1</a></li>
    <li><a href="#" data-options="iconCls:'icon-cancel'">Option 2</a></li>
</ul>

Trees

Trees are used to display hierarchical data in a tree-like structure.

Example

<ul id="tree" class="easyui-tree">
    <li data-options="iconCls:'icon-1'">Node 1
        <ul>
            <li data-options="iconCls:'icon-2'">Sub-Node 1.1</li>
            <li data-options="iconCls:'icon-2'">Sub-Node 1.2</li>
        </ul>
    </li>
    <li data-options="iconCls:'icon-1'">Node 2</li>
</ul>
