Multi-select list filtering
1) I want to use a multi-select list to assign categories to a list of items, then use the same multi-select list to filter the list by checking off categories.
2) It doesn't seem possible to filter using the multi-select list. You can only filter using the column header filter list, which is not the same thing and doesn't work the way it should (in my opinion).
Example: I have a list of 4 items that can be assigned to 4 categories. The assignments are:
Item 1 = Cat-1
Item 2 = Cat-2
Item 3 = Cat-1, Cat-4
Item 4 = Cat-2, Cat-3, Cat-4
Problem 1: The column header filter displays a separate entry for each unique entry. So instead of showing a list of 4 categories to pick from, it displays each category AND each combination
