Hi. Is it possible to create a filter pane list that requires a user to select at least one item. No item should be set as default. However, a user must select at least one . (The results would then be used to filter the selection values in a second filters.)
Example:
Filter List 1
Car Brands
Ford x--selected Ford
Honda
Hyundai
Lincoln
Filter List 2
Models
Mustang
Explorer
F1-50
