Creating a filter within a collection
I would like to know how to create a filter Within the collection.
I have a parameter "alloys Group". Each group of alloys may contain alloy elements. This would be easy to's with the Cascading combo, but I need to add These elements in the collection que does not allow me to use cascading combo and the values of this combo should be filtered to my selection
Alloy Group entity should preferably be out of my collection.
I believe we should use filter expressions, Could help me?

Elements to add
