Shopify's collection list can only have one with the URL "/collections", but there are cases when you want to display multiple collections. In such cases, you can use a method to display a "Collection List" section in a newly created template. This is convenient because you can manage it from the editor without writing code.
There is only one collection list template (it cannot be duplicated)

Create a new collection template and turn off the normal collections feature to display the collections list section

Select the newly created template on the collection page and reflect it on the screen.
