Hiding data or values based on selection

[AaronGlenn10]

I have a dashboard containing restaurants sales across the State of Texas -- when a user selects a City then the top performing location for that City will display [see below[ - however, when a user selects a Individual Location/Restaurant then it returns the name of that restaurant and a (Blank) for the value [see below].  Is there a way for the entire section to be blank when an invidual location is selected instead of a City [will all locations selected under that City]?

Here is the measure I'm using to return top performing restaurant in the Selected City ->

TopLocationSales = calculate([TABC Sales (CY)],KEEPFILTERS((topn(1, all (TABC[Location Name/City/Number]), [TABC Sales (CY)]))))

Hi @AaronGlenn10 

You could use HASONEVALUE function (DAX) in an IF condition in your measure. Below is an example.

Measure 2 = IF(HASONEVALUE('Table (4)'[Item]),BLANK(),[Measure])

In your scenario, you could try

IF(HASONEVALUE('Table (4)'[Location Name]),BLANK(),[TopLocationSales])
