Using EE 2.5.5. I have a products channel with three category groups associated. How do I insure at least one category from each group is selected when the user adds or edits a product entry? Is there some form validation mechanism I missed?

Check out the very useful Category Field addon.

From the Devot:ee description: "This field type allows you [to] organize your category groups as you would any other custom field type anywhere on your publish entries form."

You could create one "Category Field" field for each of your 3 category groups and make these fields required in the channel field settings, which I believe would accomplish your goal.


The BW Required Category addon will do the trick to makes categories required for specified channels.

  • Disappointed that rep from other StackExchange properties don't count here. (Not that I have oodles elsewhere either, but at least I could vote and such.) But will do. Mar 14, 2013 at 16:32
  • They want people to gain rep by subject which is why it doesn't transfer.
