I'm looking for help with the filter widget, in particular filtering values by previous expressions. I’d like to set up filters on two fields that contain multiple values delimited by a semicolon. For the first filter, I’d like the user to be able to select one or more options from a list of predefined multiple values and I’d like that selection to filter the available values in the second filter. Is this capability available for contains clause with multiple predefined values? The filter widget documentation seems to imply that it should be, but I’m not seeing the option to do so in the expression builder. When I switch the clause to “is” I do see the option to filter by previous expression, but this won’t work for my field which contains multiple delimited values. Is this expected behavior?
