title: How do you save data to database using EXT: Form in TYPO3 8.7.1?
body: <p>I need to create a contact form to allow users to send emails. Data must be saved in the database and notification send to the user. So far, I've been using EXT: Powermail, which works fine. In current project I'm using TYPO3 8.7.1 and I'd like to use EXT: Form 8.7.0. I've a test installation based on Introduction Package. I'm using predefined "Contact Form", but in the edition mode, I can't select finisher "Save to database". The only finishers I can see are: email to sender, redirect to a page, delete uploads.</p>
  
  <ul>
  <li>how to enable finisher to save form data into database? and where to select "Storage Id"?</li>
  <li>is it possible to list all records (emails) in List module similar as it is in Powermail extension?</li>
  </ul>
  
  <p>I've been searching for some tips in a documentation, but couldn't find that. </p>
