Supply's 'advanced tag filtering' with more control of the listing order AND view more functionality

readme.md

Group Sorting:

• There is a text field in the theme settings where you list the tag prefixes with no underscores. (ex: Size,Price,Color)
• All groups must be mentioned in that input field in order to appear.

Individual List Sorting:

• This requires the use of a Link List in the Navigation area of the Admin
• The list name is 'reorder_' with the tag prefix to represent the group of tags you want to manually sort. ie Reorder_Size
• Each link inside this list is the full product tag with prefix and underscore directly the same as in the product page.
• Only the lists that you want to sort manually need to be created or else it will just use the normal sorting of the list
• See image below as an example:

Setting this up

• You want to find <div class="grid-uniform"> in the collection-sidebar.liquid and replace that section (approx lines 13-44) with what I have above.

collection-sidebar.liquid

    <div class="grid-uniform">

Is there a way to tell it to hide the entire group if sidebar-module__list is empty? For example, I have a website where one category uses a certain group that I've added to the sidebar, but a different category doesn't use that group so it shows up in the sidebar needlessly. Is there a way to fix this?

Loving this, btw! It's super helpful!

I have the same issue as Aim828. Is there any solution to this? Thanks!

Any word on this? I'd love to use it on my site, but if I can't get rid of the extra groups then I can't really use it since it looks awkward.
