Enabling the Form Design Toolbar
The first step to creating a form is making the necessary tools visible. By default, LibreOffice Writer hides advanced design features to keep the interface clean. You need to manually activate the specific toolbar that contains form controls. Go to the View menu at the top of the window. From the dropdown list, select Toolbars. In the submenu that appears, check the box next to Form Design. A new floating or docked toolbar will appear, typically containing icons for buttons, text fields, checkboxes, and combo boxes. If this toolbar does not appear immediately, ensure you are not in Print Preview mode, as form controls are only editable in Normal view.Drawing and Configuring Form Controls
Once the Form Design toolbar is active, you can place interactive elements into your document. Click on the icon representing the control you wish to add, such as the Text Field for user input or the Checkbox for yes/no options. Your cursor will change to a crosshair. Click and drag on the document page to draw the field to your desired size. After placing the field, you can customize its behavior by right-clicking the control and selecting Control.... This opens a dialog where you can set properties like the field name, default value, and whether it is required. For example, you might set a text field to accept only numbers or limit the character count for an email address. It is crucial to give each control a unique name if you plan to extract data later, though this is optional for simple visual forms.Exiting Design Mode
A common mistake is leaving the form in editing mode when sending it to others. While in design mode, users cannot click inside the fields to type; they can only move or resize them. To finalize the form, you must toggle off the design mode. Look for the button on the Form Design toolbar that looks like a pencil over a sheet of paper, often labeled Design Mode. Click this button to deactivate it. The background grid lines and selection handles around your controls should disappear. At this point, you can test the form by clicking into the text boxes and typing. If the controls still behave like static images or allow resizing, double-check that design mode is truly off.Exporting to PDF
To share your form, you must convert it to a format that preserves interactivity. LibreOffice Writer supports exporting directly to PDF while maintaining form field functionality. Go to File and select Export as PDF. In the PDF Options dialog, navigate to the General tab. Ensure that Create PDF Form is checked. This setting is critical because it tells the exporter to preserve the interactive nature of the controls rather than flattening them into static graphics. You can also choose to include bookmarks or cover pages here. Once configured, click Export and save the file. The resulting PDF will open in Adobe Acrobat Reader or other compatible viewers, allowing users to type into the fields you created.Writing with a Pencil Tablet
If you intend for users to sign or write by hand on the form, standard text fields will not suffice. Instead, use the Picture Control from the Form Design toolbar. Draw a rectangle where you want the signature to appear. When exported to PDF, some viewers allow users to draw directly over this area if the appropriate annotation tools are enabled. However, note that handwriting recognition varies significantly between devices. For tablets like an iPad, users may need to use a stylus and a PDF annotation app to draw freely. Text fields remain the most reliable method for structured data entry across all platforms.

Why can't I type into my form fields?
You likely have Design Mode still enabled. Toggle the Design Mode button off in the Form Design toolbar to switch from editing controls to using them.
Do form fields work in all PDF readers?
Most modern PDF readers like Adobe Acrobat Reader support standard form fields. However, older or mobile-specific viewers may flatten the form, making it non-interactive.
How do I make a field read-only?
Right-click the control, select Control Properties, and look for the "Read-only" or "Enabled" checkbox. Unchecking "Enabled" or checking "Read-only" prevents user input.
Can I add a date picker control?
LibreOffice has a Date Field control in the Form Design toolbar. Select it and draw it on your page to allow users to pick dates via a calendar widget.
What if my PDF form looks broken on mobile?
Mobile screens often struggle with small form fields. Test your PDF on a tablet or phone and consider enlarging the field sizes during the design phase for better usability.
