I have a vertical gallery, "Gallery3", and a horizontal gallery "gallery7" nested in that gallery. I followed Reza's tutorial and the items in gallery3 are defined by a choice column, Choices(DataSource.ColumnName)
My problem is that Gallery3 has all choice options "showing" when my horizontal gallery is blank. How do I filter out items/rows of gallery3 when gallery7 is blank? Is this possible?
Alternatively, I could sort by the number of items in each horizontal gallery then sort by descending such that empty rows in gallery3 are at the bottom...but I am yet to figure this out too
Try this in the Gallery 3 Items
