How to Fix Missing Calendar and Button Fields in Acrobat PDF Forms
Question details
Users are unable to locate or insert calendar (date picker) and button fields when attempting to edit a PDF form.

- Product
- Adobe Acrobat
- Device & OS
- not provided
- Scenario
- Editing a PDF document to add interactive form elements like date pickers or buttons.
- Observed behavior
- The standard form tools, specifically calendar and button fields, are missing or greyed out because the document is actively being edited as an e-sign form rather than a standard PDF form.
Ensure you have the necessary editing permissions for the PDF document and verify that you are not currently in the middle of a live e-signing workflow that prevents structural form modifications.
Revert the E-Sign Form to a Standard Acrobat Form
Switching the document format back from an e-sign form to a standard Acrobat form will immediately restore access to all interactive form fields, including date pickers and buttons.
When a document is optimized for e-signatures, Adobe Acrobat restricts certain interactive fields to streamline the signing process. Reverting the form type removes these restrictions.
Open your PDF document in Adobe Acrobat. Click on 'Tools' in the top navigation menu, then locate and select 'Prepare Form'.
Navigate to the right-hand pane of the Prepare Form interface and click on the 'More' option to reveal advanced form settings.
Select 'Revert to Acrobat Form' from the drop-down menu. Your standard form tools, including the calendar (date field) and button fields, will now be visible and ready to use.

Create and Edit Interactive PDF Forms with WPS Office
WPS Office provides a comprehensive suite of PDF tools, allowing you to easily add interactive elements like text fields, checkboxes, and push buttons to your PDF documents without complex format restrictions.
- 1. Open your PDF in WPS: Launch WPS Office and open your PDF document using the built-in PDF editor.
- 2. Access Form tools: Navigate to the 'Form' tab in the top ribbon to view all available interactive form fields.
- 3. Insert form fields: Click on the desired field type, such as a Text Field, Check Box, or Push Button, then click on the document page to place it.
- 4. Customize properties: Double-click the inserted field to open the properties panel, where you can customize its appearance, name, and behavior.

Frequently Asked Questions
Why did my PDF automatically convert to an e-sign form?
Adobe Acrobat may automatically convert standard forms to e-sign forms if you initiate the 'Request Signatures' tool or if the document was previously saved and distributed as an Adobe Sign web form.
Will reverting to an Acrobat Form delete existing signatures?
If your document already contains active digital signatures or has been finalized for e-signing, reverting it to a standard form may invalidate those signatures or disrupt the current e-signing workflow.
Are button fields supported in all PDF viewers?
While standard interactive fields like buttons and text boxes are widely supported in major PDF editors like Acrobat and WPS PDF, some basic web browsers or default mobile PDF viewers may not fully support their interactive functions.
