Smarter collection filters

Two changes to the filters on collection pages.

Product type stays selected. A menu link that opens one product type, such as Suppressors, now shows a ticked Product type filter. Adding a caliber or any other filter keeps it, so choosing 9mm narrows the suppressors instead of switching to every 9mm product in the store. Ticking a second type widens the results to either type. See Filters on collection pages.

AI clients can curate your filters. With nothing selected in the theme’s Collection Filters setting, every specification in your catalog becomes a filter, which on a distributor catalog can mean hundreds of dropdowns. Two new Theme Dev MCP tools let an AI client do the choosing. list-collection-filters shows every specification group with how many products carry it, its most common values and the product types it applies to. set-collection-filters saves the chosen groups to the theme, rejecting any name your catalog does not have.
