I want to make a marketplace where members can sell their own products. How do I allow them to post themselves?
You can create a collection with the fields you need (product name, image, price, owner name …), allow members to submit and read from this collection (in the collection settings) ,
Then create a form (with user input) and connect it to your collection (so when a user fills out the form, the information will be uploaded to your collaction).
Next, you’ll connect a repeater to the same collection so you can show what users are posting to the collection.

Is there a video, I know this is still in BETA?
I believe this feature is not yet available on Wix. It might work as mentioned by the user oussamaismaili7, but we need to consider the challenge of handling payments for thousands of vendors on a monthly basis.
One possible solution is to set a specific day each month to pay each vendor their earnings. Doing this manually would be a daunting task.
Alternatively, you could explore using a Multi-Vendor website builder specialized in creating online marketplaces, similar to platforms like Udemy, Amazon, Airbnb, CGTrader, Etsy, and many others.
These marketplace builders also provide vendors with valuable insights into their business performance within your marketplace.
