Hi Hugh, sorry for the delay: I made some tests but it is still not working for me.
Storing Torneo in db just saves the value of the element, but it's not what I need to save: this element is meant to be only a filter for the dropdown element.
The issue is that it does save the multiple selection, but "only the first time" - meaning that it saves everytime, but everytime it is like is the first one.
It doesn't reload it (or if does, it doesn't show as "selected" the already made selection) if you edit the field again and the Torneo element is saved in the DB.
The same thing happen if you:
1)filter the dropdown by value 1,
2)select one entry,
3)filter the dropdown by value 2,
4)filter the dropdown by value 1,
at this point the selection made at step 2 is "not selected"
Maybe I should save after I make my selection (step 2 of the previous list) but if I then want to select some more entries, I miss the previously selected entries.
Am I doing something wrong? Is it not supposed to work like that?
Thanks
