How to make a callback forum on Joomla 3.6.3?

Question

Joomla

There is a landing page with one form directly on the page and one form that opens in a modal window. Both forms have the same functionality. Is it possible to make requests come to the admin panel in one place and which official extension is better to use for this?
What is the difficulty? I looked in Google there in the top to solve a similar problem, everyone uses different extensions while downloading them from different resources that do not inspire confidence, in my opinion. Is there an official or semi-official extension, preferably free and preferably with adequate documentation?

Answer 1

There is an official extension directory
https://extensions.joomla.org/ extensions from the directory can be trusted. I advise you chronoforms 5, but the only thing is that the extension sends the form to the mail, and not to the database.
