I want the filter optional to show or hide +/-, as in the Mobile View.

Hello Claude Meury,

You can hide it manually through css.
category filter box has class="categoryFilter"
You should open file: ftp://templates>>your_template>>css>>style.css find line: @media screen and (max-width: 767px) {

and after add new code:

Code:

---

Only registered members can view the code.

save and check again.
