Додади поле

Opens a window where you can select a database field to add to the form.

The field selection window lists all database fields of the table or query that was specified as the data source in the Form Properties.

You can incorporate a field into the current document by dragging and dropping it into the document while holding down the mouse button. A corresponding field is then set up in the document with a link to the database.

If you switch off the Design Mode, you can see that LibreOffice sets up a labeled input field for every inserted database field where the user can enter the data.
