I need to create a filtering mechanism and I'm attempting to figure out the best way to do it. Yes, I have a post to the Filter forum... but I'm likely going to be told that it is more complex than what the users will want. So, I have a menu bound to a collection of user-defined Templates as shown. Each Template has multiple Items as bound to the children/sub-menu.
As the user selects options from this menu, I need to retain the Child Item's Id in order to build a Filter set that I can submit to a REST service. Because the menu will not provide feedback like your Filter control, I'll need to display the filter in a field that'll grow as they add criteria much like the "ExpressionPreview" on the Filter control.
