How can I change the number of columns displayed on the Course (or Membership) Catalog?
The LifterLMS Course and Membership Catalogs organize content into 3 columns by default. If you’d like to modify the number of columns, you can do so by adding this code snippet to your theme’s functions.php file or to a custom plugin.
Note that LifterLMS’s CSS supports 1 to 6 columns. If you require 7 or more columns you will need to add custom CSS to accommodate.
