.handle(state, key, group, _force)
This method will change the state (first argument) on the passed option. Use "select",
"unselect", "enable" or "disable" as first parameter to "set" the respective state. The
fourth argument forces / skips the "don't unselect an option on single select fields, which
aren't deselectable" condition.
Clicking the "Select Values" button will select "Jeep", "Tesla" and "Dodge".
