9.4.9 Select Menu (std_dropdown)
The select menu is based on a native select element, which is hidden from view and replaced with a custom-styled select button that matches the look and feel of the jQuery Mobile framework.
By default, the framework leverages the native OS options menu to use with the custom button. When the button is clicked, the native OS menu will open. When a value is selected and the menu closes, the custom button's text is updated to match the selected value.
The Select Menu weblet also offers the option of generating custom menus instead of the native OS menu. The custom menu supports disabled options, multiple selection (whereas native mobile OS support for both is inconsistent) and adds an elegant way to handle placeholder values. See the useNativeControl property for details.
