The reason why we have 2,3,4 and 6 columns is in bootstrap grid http://getbootstrap.com/css/#grid. As you may see in their documentation there is no 5 columns grid as well as in the Visual Composer functionality.
If you anyway need 5 columns for your shop page we can try to help you with this small customization. Please set up chil theme and provide your FTP access to the site.
Hi!!!
My client would like also to have 5 columns in shop page.
Could you explain to me how can I do the customizations for that, or maybe, I can send you credentials for the website…
