I am trying to ENABLE/Edit sort by state in a listbox. The listbox contains a hierarchy split up by '>' which works well. Since there are a lot of possible values to be selected, I want the sort by state feature enabled so users can quickly see what they are filtered on. Unfortunately, this option is completely grayed out. In the past, I have been able to get around this by remaking the listbox, but now that trick isn't working anymore.
Anyone have any inputs on this or maybe some insight to the functionality/limitations of this feature?
