Hi,
In a panel there is a possibility to create dropdown list with drag and drop + SHIFT:

It’s working as expected but I want to have in my drop down all possibilities that can be contained in the dimension Search Term.
I know it’s possible by adding them one by one:

If I drop the dimension, the filter is only about this dimensions exists:

But in my case I want to make it dynamic, meaning, I want to have all possible values that can be contained in this dimension: if a new value is present, it’s automatically added in the dropdown.
How can I do that?
Thanks
Robin
