Atleast show one value when clear filter applied

[Karim_Khan]

Hi Team,

I am working on one of the requirement where we want to show atleast one value should be selected by default and we can have option to select as many fields from list box.

But when we apply clear option then atleast one value should be selected in list box and rest can be cleared.

I tried Always select one value option but it will not allow to select more than one fields due to its functionality.

I know it's achievable in qlikview through triggers but its not working in QlikSense.Any suggestion appreciated here.

We tried with Select field variable in Qlikview but no luck with Qliksense

Expression : =If(GetSelectedCount(LIST)=0,MaxString({$1}LIST),'('&Concat(LIST,'|')&')')
