Hello all, perhaps someone has a good idea how I can fix my issue.

I use an external tool to administrate calendars. With batch und hourly import to Joomla the events will be updated. Events have one or more categories. The categories are visible in database. Import works fine.

To generalize the issue I describe it with Category A, B and C

In Joomla-Menü there are Menue-Items to show Cat A, a second one with Cat B, and third with Cat C records.

But sometime the CatA and CatB are in relation. So I want to filter such records for the view where Cat A + Cat B are set.

At the moment I can add CAT A and CAT B to the Filter, but than I got result from addition A + B. How I could filter to such records where both Categories are set?

Hope it is understandable.

Best regards
Michael
