Detailed Description
The CategoryMenu widget aids in filtering records or files by Category.The CategoryMenu widget provides a popup menu that will make filtering records or files by category much easier. The widget will lookup the available categories for an application, populate the menu, and keep a track of which categories are being filtered against. A set of categories can be tested by the isSelected() function to see if a record or file containing those categories would be allowed through by the filter.
