Filtering Nested galleries

Posted on by JamesOwen

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

Filter( ForAll( Choices(DataSource.ColumnName) As _choices, If( !IsEmpty( Filter( DataSource, ColumnName.Value = _choices.Value ) ), {Value: _choices.Value} ) ), !IsBlank(Value) )
