In the example I send with this message you see cells K12 and K13 to be red
When I perform a filtering on "colour red" I want to see of course Rows12 and 13 (with the red rectangle) but also the title above these items (the rows with 1.1 and 1)
the item 1.2 has 2 red rectangles so everyting must be displayed
the item 1.3 has no recatngel so everything should disapear
