Horizontal filters, with multiple selections

hi,
I'm looking to throw a horizontal filter to hide colomns depend on row 3's value.

I googled and found;

Great if you only have 1 selection.

But, I'd like to have the selection be like a regular filter, with multiple selections.


Any ideas?

I haven't made any progress. I'm close to redoing the whole spreadsheet vertically instead, align the text vertically and so forth HA!
