Limit Selections in filter to one

[#1]

Hi,

I have a filter with merchant data. How can I limit an user to select only one value from filter drop down?

I do not want user to select multiple merchant names in the Filter List.

Please advise. Thanks.

5 years later, is this still not a thing? I have a requirement to have the user make multiple selections before a table appears and displaying each selection option is dependant on the previous one being selected before it appears, but I do not want to force a selection to be already made the instant the user enters the app or that will enable the second selection to appear already.
