Field Parameter Drill Depth

[music43]

Hi

Is there a way to stop the drill level changing when using field parameters this way? 

I am trying to mix fields that can be logically grouped but some have different depth hierarchy (e.g. Brand is 1 level but Product Category > Sub Category > Code is 3 levels)

Data Model

Field Parameter (extended)

Sample file 

Any suggestions welcomed.

Thanks

Oli

There is not a way to have the visual automatically expand to drill down when the field parameter is changed. The users will have to expand the visual. You could have it set to where the Product Grouping is the default view and expanded like you have it shown in the first screenshot - then anytime someone wants to go back to that view after they changed it (but they don't want to expand it themselves) they can simply click the reset to default icon at the top of the screen in service.
