LISTBOX.popUp
[The feature associated with this page, Windows Media Player SDK, is a legacy feature. It has been superseded by MediaPlayer. MediaPlayer has been optimized for Windows 10 and Windows 11. Microsoft strongly recommends that new code use MediaPlayer instead of Windows Media Player SDK, when possible. Microsoft suggests that existing code that uses the legacy APIs be rewritten to use the new APIs if possible.]
The popUp attribute specifies a value indicating whether the element represents a popup or list box control.
<ELEMENT popUp="value">
Possible Values
This attribute is a Boolean specified at design time only.

Remarks
The POPUP element represents a list box control that is displayed only when needed. It is identical to the LISTBOX element except for the default value of this attribute, which changes the display behavior. For LISTBOX elements, the default value is false. For POPUP elements, the default value is true. Instead of specifying this attribute, the LISTBOX or POPUP element should be used to according to the desired behavior.
