WordPress Plugin to display a list of input fields which are visible to everyone?

I am looking for a plugin/workaround recommendations. I am sorry if the title was not descriptive enough, this is the best I could think of. Any edit suggestion is welcome.

I want to display a list of editable text fields, which are updated by any visitor, and all updates are live and public to everyone else. The submitted fields may or may not be editable anymore.

So, once a visitor visits the page, there will be a list of empty blanks/fields, short text fields for instance. They will fill in their name and their details, then submit. All other visitors will see that this field is taken/filled.

The reason is that there will be a list of offerings, and the link will be distributed among participants only, each participant can fill a “slot” with their details after seeing which slots are available.

I don’t need any extra validation or complexity. Logging in is not required.
