<div class="textblock"><p>A menu presented in a popup window. </p>
<p>A menu is always presented in a popup window, and, unlike other widgets, cannot be instantiated on its own (by adding to a <a class="el" href="classWt_1_1WContainerWidget.html" title="A widget that holds and manages child widgets.">WContainerWidget</a>). Instead it must be associated with a <a class="el" href="classWt_1_1Ext_1_1Button.html" title="A button.">Button</a> or <a class="el" href="classWt_1_1Ext_1_1MenuItem.html" title="An item in a menu.">MenuItem</a> (to create sub menus).</p>
