In the first row of my spreadsheet I have 3 values: B, LL and LK
I want to be able to filter the sheet on one of these values BUT, the title of the items shoul be seen as well:
example
in the attachement
when I choose to filter on LK I get to see all LK items together with their title (in this case 2.12) (and finally title 2 as well)
choose B I see all "B-items" with title 2.10 and 2.11 (and also title 2)
