Hi Eran-
Thanks for the great question, and thanks for using the BoldGrid Post and Page Builder for WordPress.
By default, video embeds don’t have any type of “Taxonomy,” or categories, out-of-the-box. You could probably design a portfolio like this manually, especially using the Audio and Video category of blocks in the block library.
I did find a free plugin, Vimeotheque, that will create Custom Posts from Vimeo links that you can then categorize for your portfolio.
