I don’t know what to call this feature, but I was wondering if there was a way to control the listed items in a category drop down by creating a dependency on another category.
For instance, the contents of one categroy drop down would be filtered based on the selected category from another drop down.
Does that make sense?
You can’t control what is available for selection of items in the filter tray. I will add your vote for this request in our database.
However, you can control the collapsed / uncollapsed state of items based on values. Take a look at the attached model file. I have set up a custom filter that inspects the values and Matrix2, and either collapses or uncollapses the items in Matrix1 based on the Matrix2 cell values.
