Set calculated filed from Dropdown Multiselect

Hi all i want to use calculated filed to show/hide columns based on some value from a dropdown- multiselect menu.
Example i have column A and B and want to select A or B or A And B and assign value to a calculated field in order to show some column or not. How can i set ifelse command in case of multiselet?

This is currently not possible.

You might look to do this with a parameter and load different visuals.

At AWS, our roadmap is primarily driven by our customers. Your feedback helps us build a better service. I have marked this as a feature request.

I hope @Max 's suggestion provides you with a potential workaround in the interim.
