Need help on a few items

Hi, I need help on the following items:

1. For the element “Show tours of attribute”, can another one be added to “Show tours of categories”

2. For mobile portrait view for Tour page (grid 3 rows with side bar), how do i make it to show 2 columns meaning 2 tour per row instead of the large 1 tour per row.

Appreciate your help!!!!
