    "description": "The PopUpMenuButton control creates a PopUpButton control with a main sub-button and a secondary sub-button. Clicking on the secondary (right) sub-button drops down a menu that can be popluated through a <code>dataProvider</code> property. Unlike the Menu and MenuBar controls, the PopUpMenuButton control supports only a single-level menu. This means that the menu cannot contain cascading submenus.  <p>The main sub-button of the PopUpMenuButton control can have a text label, an icon, or both on its face. When a user selects an item from the drop-down menu or clicks the main button of the PopUpMenuButton control, the control dispatches an <code>itemClick</code> event. When a user clicks the main button of the control, the control also dispatches a <code>click</code> event. You can customize the look of a PopUpMenuButton control.</p>  <p>The PopUpMenuButton control has the following sizing characteristics:</p> <table class=&quot;innertable&quot;> <tr> <th>Characteristic</th> <th>Description</th> </tr> <tr> <td>Default size</td> <td>Sufficient to accommodate the label and any icon on the main button, and the icon on the pop-up button. The control does not reserve space for the menu.</td> </tr> <tr> <td>Minimum size</td> <td>0 pixels.</td> </tr> <tr> <td>Maximum size</td> <td>10000 by 10000.</td> </tr> </table>   <p>The <code>&lt;mx:PopUpMenuButton&gt;</code> tag inherits all of the tag attributes of its superclass, and adds the following tag attributes:</p>  <pre>\\n &lt;mx:PopUpMenuButton\\n <strong>Properties</strong>\\n dataDescriptor=&quot;<i>instance of DefaultDataDescriptor</i>&quot;\\n dataProvider=&quot;undefined&quot;\\n iconField=&quot;icon&quot;\\n iconFunction=&quot;undefined&quot;\\n labelField=&quot;label&quot;\\n labelFunction=&quot;undefined&quot;\\n showRoot=&quot;false|true&quot;\\n &nbsp;\\n <strong>Event</strong>\\n change=<i>No default</i>\\n /&gt;\\n </pre>",
