list selection of participants

Give them a checkbox field that allows them to select to hide their record from the list, then include that in the shortcode filter.

Can I use Participants-database as a member selection base?

I explain:

If some external organisation want to questioning some of my members who have indicated that they will be attend paid questioning requests.

Those members have given first answers in fields like: sex, married, school, country, city, cell, age, etc, etc.

Can I let an external organisation make selections in the Participants-database to learn how many participants are married, without getting access to the participants details?

If yes, can the external organisation make also relational queries like married > sex > country > age > etc., without getting access to the participants details?

Well, of course these things are rather easily done by a developer, you can create a function that queries the database to extract the information you’re looking for.

If you don’t have access to a programmer, you can possibly simulate what you’re looking for by setting up the list shortcode so it won’t show anything until a search is made. If you use “show_totals” in the shortcode, it will show how many records matched the search, so if you wanted, you could set it up so only that number was displayed.

Check out the docs for how to set up your shortcode so it only displays results after a search…https://www.ads-software.com/extend/plugins/participants-database/other_notes/
