I can’t create a nested Product collection in Categories on a static page. I just want a page with all products grouped by collections. When I add a collection list to a product Categories collection list, Webflow doesn’t allow me to connect the Products source. I get “Please add a multi-reference or muli
image field to the Categories Collection to add a source.”
Unfortunately, nested collection lists only work with multi-reference fields. The problem you’re facing isn’t related to Product, it’s related to how Products and Categories are related.
You basically have these options.
Skip nesting, and instead list your products on the Category page.
Skip nesting, list products, with category as an attribute. You can sort them by attribute, but not “group” them.
Skip nesting, and have a separate collection list for each Category. Filter the products so that only the ones in that category show.
Emit your products and collections together, and then use script to restructure them in a grouped fashion.
