How to Create Optional Dimensions in Looker Studio Like Optional Metrics?

[Sumeet Yadav]

I know that optional metrics allow users to select which metrics to display. Is there a way to create optional dimensions, where users can check boxes or use a drop-down to choose which dimensions appear in the table?

I imagine a solution where users can dynamically toggle dimensions (like "Category", "City", "Region", etc.), similar to how optional metrics work. Has anyone implemented something like this?

There is a way to do it. 

You can use dimension control, after you add this control, group it with the desired chart/s to change the dimension only for them.
