The collections list settings contain all the settings/sections you need to configure your collection list pages. You can build your own collection liste page from scratch, but ofcourse we've provided the theme with a default collection list page.
How to edit the collections list?
The collection list page contains of sections and blocks, these sections and blocks can be added, editted and removed. You can use all the sections that are used on the homepage. There are not really specific elements for the collection list pages. But it is nice to have a template you can work with!
First you'll have to navigate to the collection list template.
You can do this by navigating to Collections list in the top bar of the theme editor
Once on this page, the default template is ready to be edited!
How to edit the page
Since the collection list does not contain specific elements, you can use the sections that are provided within the theme. Simply click on 'add section' or within a section 'add block' to implement the elements you wish.
Information about the sections and how to set them up can be found in the documentation here
