Show dependant sub cats on a ui action

[joshmorris]

I have wrote this script in a UI action to resolve a ticket. I have listed all of my categories on it. The question I have is how do I get it so the dependent sub categories will show based on the category selected.

Thanks for this but I really wouldn't know where to start with this

Step 2 is the tricky one, please check if OOTB ServiceNow gives some onchange event for the field added on g_modal

If my response helped please mark it correct and close the thread so that it benefits future readers.
