I created two CMS collections in Webflow, one for a blog and one for categories. I imported all the categories from wordpress to the categories CMS collection. In the blog CMS collection I added a Multi-reference field and connected it to the categories collection. When I import the blog posts into the blog CMS I am able to map all the fields except that one, it will not add the categories. Each blog post I am importing has a few categories associated with it. Just as an test I stripped out the multiple categories and just left one for each blog post. Still will not import. The categories are exact matches between the two collections. Any one have experience with this?
Are you using the category slugs? Best way to check is to manually create a few references and CSV export to see Webflow’s format, but I would guess that it’s typically semicolon-separated, e.g.
My Article,cat-1;cat-2;cat-3,Author
Or quoted comma-sep, like;
My Article,"cat-1,cat-2,cat-3",Author
