I am guessing this will all have to be custom code but maybe slight hope there is already a solution available. My problem is filtering of my CMS Collection by referenced Collections.
(1) If you look at my CMS collections you will see: Cruise Packages
(2) Within Cruise Packages there are four reference fields (Bottom of list)
(3) On the page ‘CruisePlus Exclusive Packages’ I have a drop down sort menu for the reference field ‘Trip Month Reference’
(4) My Question: How can I get the collection list to only show the collection items that have a connection to Cruise Packages Items. (Right now Cruise Package items are only using 6 of the Trip Month Reference items).
