Hello, i had another issue with buttons and you gave me this answer https://www.joomlart.com/forums/d/29388-buttons-in-login-have-other-colour/2
My issue now is that when i must use the option in this eshop extension Load Bootstrap CSS "No" then the categories and maybe products of this extension are not full responsive .
What i mean? When i use Load Bootstrap CSS "Yes" in mobile view the categories are display in 1 column but when i use Load Bootstrap CSS "No" as you recommended to make, the categories are display in 3 columns. If for example i want to use 4 columns some categories are not display well in mobile. I put 4*Default Items Per Row (4 columns) to display the issue better.
