Multi select with cascading logic
I have a parameter list that drives (cascade) a second parameter list.
The parent has 100 or so selections.
Each parent has 100 or so associated selections in the child list.
This makes the child list a few thousand values long.
I am able to set up the cascading logic for two combo boxes in a table using form addition.
I am unable to make the second combo a multi select. (it allows me to change it to multi but seems to always remove the cascading logic)
Is there any way to implement this so that the presentation of the child values is filtered based on the selection of the parent, and allows for selection of multiple values in the child parameter.
