Create a Standard Acrobat Form Instead of an Adobe Sign Form

Switching your document format from an Adobe Sign form to a standard Acrobat form unlocks advanced form-field properties and calculation options.

Adobe Sign forms are strictly optimized for e-signature workflows, which intentionally restricts complex interactive elements. To use advanced tools like the Calendar picker and Calculate functions, the document must be configured as a standard Acrobat form.

Launch the desktop version of Acrobat Pro

Open the Adobe Acrobat Pro desktop application. Web versions have limited form capabilities and do not support advanced property editing.

Open the Prepare Form tool

Navigate to the 'Tools' tab at the top of the interface and select 'Prepare Form' to begin editing your document.

Select standard Acrobat Form

When configuring the form, ensure you choose to create a standard 'Acrobat form'. Do not select or check the 'Adobe Sign form' option.

Access advanced properties

Right-click on your date or text fields and select 'Properties'. You will now see the 'Calculate' tab and formatting options to enable the calendar picker.

Tool Availability: If you already created the document as an Adobe Sign form, you may need to revert it or recreate the form fields in a standard Acrobat PDF environment to restore these tools.

Frequently Asked Questions

Why doesn't the calendar picker show up on my date fields in Acrobat?

This usually happens because the document was created as an Adobe Sign form. Adobe Sign format restricts certain interactive elements. Recreating the document as a standard Acrobat form will restore the calendar dropdown for date fields.

Why is the Calculate tab missing in my Acrobat form properties?

The Calculate tab is only accessible when working on a standard Acrobat form using the desktop version of Adobe Acrobat Pro. It will not appear if you are using the web version or if the file is set as an Adobe Sign form.

Can I access advanced Prepare Form tools on Acrobat Web?

No, the web version of Acrobat provides only basic form-filling and creation tools. For advanced properties, custom formatting, and calculation options, you must use the desktop Acrobat Prepare Form tool.
