Mega-menu on an Artist website, and member list

Hi Webflow!

Is there anyone here who can help me find a video or something so that I can make a Mega Menu with Webflow?

The point is that a website must be created for visual artists, and there are approx. 50 members, each of which must have its own underside.

And is it so that Webflow can make such a “Member list” Billedkunstnernes forbund, - where these visual artists who are members can log on to their own page, and change images and text, etc. ?
I’m thinking of making it every artist as a CMS. (But can all these log on to his CMS page?)

I have to answer my client whether this can be done in Webflow by tomorrow.
Thank you very much if someone could answer me quickly.
