I am creating a form through the Libre Office forms design tool, but I can not find the way to mark the fields as required, so when I generate the .html, whenever I click on the submit button the form is sent.
The only thing I have seen about it is the "Data" tab of the properties, but it is necessary to associate a database and it still does not work, it does not force me to fill in the field in question. I've tried it with the example table provided by the office tool.
