I've set up some conditional category select fields:
1: Select type A or B
show only if type=A: 2: Select category type 1
show only if type=B: 3: Select category type 2
The user interface works great, but I find that values of hidden category select fields are posted and stored, which can potentially leave 'dirty' information in my database.
A scenario to recreate this:
- Select type A
- Field 2 is shown, select a category
- Select type B
- Field 2 is hidden, field 3 is shown. Select a category
- Submit the form
Now values for both field 1,2 and 3 are submitted and stored.
