Is it possible to use some code to create a page with a list of categories instead of a list of entries?
I mean, I need to create a grid with the different categories of a custom post type, and when clicking on one, access the list of posts of that category.
If this is not possible with this plugin, or by adding code, I would appreciate any alternative.
I’m afraid it’s not possible with the plugin as it is created for listing posts rather than taxonomies.
While you can try creating a custom post type that’s sole purpose is to list categories and make WP Show Posts display them with links redirecting to category archives, this isn’t optimal.
You can try listing your categories by using the wp_list_categories function.
