Any LibreOffice document can be expanded into a form. Simply add one or more form controls.
Open the Form Controls toolbar. The Form Controls toolbar contains the functions needed to edit a form. More functions can be found in the Form Design bar and More Controls bar.
The Form Navigator icon on the Form Design bar opens the Form Navigator.
The Open in Design Mode icon allows you to save a form document so that it always opens in form design mode.
If there is an error when assigning properties to the objects contained in the form (for example, when assigning a non-existent database table to an object), a corresponding error message appears. This error message may contain a More button. If you click on More, a dialog displaying more information about the current problem appears.
