Now that Webflow implemented the first phase of static file uploads in the Asset Manager, we need to add the ability to upload the new types of non-image assets via the Webflow CMS.
It should be possible for clients to upload/change files/attachments via the Editor interface as well.
Great news: we've shipped this! Now live for all sites with CMS and Business hosting (and sites on staging if you're just trying it out). Read more on our updates page.
