theming – Show result of current selected value in drupal 8 better expose filter used multiple filter

I want to pass only the current selected value/ want result of current selected value even if there previous selected value in Better expose filter.

I have taxonomy term with multiple term that I using in the view.

Say A B c D E having terms A – A1, A2, A3 B- B1, B2, B3 and so on

If user select A2 then he select B3 the data should shown on B3

Means previous selected terms value should not be shown only the current selected term related value should be shown
