You can put collection pages under a static folder, but in your example above, I’m assuming brand, category, and product-name would be dynamic labels coming from the CMS or the ECommerce Products catalog.
Unfortunately, Webflow doesn’t support multiple levels of dynamic URLs like this.
The only way I can think of doing this on a Webflow-hosted site is to setup a reverse proxy that maps URLs like so;
You see this technique done in blogs a lot- in your URL structure, the brand and category are just SEO-candy and eye-candy - they are not needed for navigation. Your reverse-proxy routing rules can ignore them, because Webflow has a unique product-slug for each item already anyway.
Then in your site links, etc, you’d need to craft them to contain that info just for Google’s benefit. In reality it’s just ignored and not part of the actual site structure.
Fair warning, this is a lot of work to setup, but hey you might have your reasons.
If you mean the URL’s, yes the path is always /collection-slug/item-slug.
With the new parent-folder ability, it can be /my-static-folder/collection-slug/item-slug however my-static-folder could be the same for every page, it cannot be dynamic.
