Can this be done with a JS? I have a form with items to be selected as shown below. And I have a SQL that brings in ALL of the supplies list data. So when PAPER is selected I would like to only see what is in PAPER category. And in SQL db I do have a field called itemcode. So that everything that is PAPER it has an itemcode called paper.  And for TAPE/TAPE DISPENSER it's called tape and so on.
