I use multiselect dropdown with values from external dictionary got from API.
User choose some options from dropdown, I save it to database through API, everything works fine.
But there is a trouble with default value. I need to get default values from the same type of data as Choices source and this is my dictionary.
Okay, but I need to filter it with user saved values. And here I can choose only single element as a constraint (not a list of them). I’ve got to compare if with list of items (saved by user in database). And there is a conflict.
As a result - empty default value.
Details you can see on screenshot.
