Quick form multiple selection feature request

In the quick form nodes that allow multiple selections such as the column filter quick form, and multi selection quick form, it would be useful to have an option in these nodes where you can enter a value range to define lower and upper limits in terms of how many or how few items the user is allowed to select.



Input validation is now possible with the newer JS based quickforms, though this feature hasn't been implemented yet.  I have opened a ticket for you regarding this.
