Check your PDF document to determine if it requires advanced interactive features like dropdown menus or automated calculations, as this dictates the type of PDF software you need to use.
Use a Capable PDF Application for Interactive Forms
Switch from the basic Adobe Fill & Sign tool to a comprehensive PDF reader that fully supports interactive form fields and JavaScript execution.
Adobe Fill & Sign is fundamentally designed for simple, flat documents and basic text overlays. It does not have the engine required to process JavaScript, macros, or advanced interactive fields.
To properly fill out these forms without losing functionality, you must use a standard, full-featured PDF viewer.
Download and install a robust application such as WPS Office or Adobe Acrobat Reader on your computer or mobile device.
Launch the newly installed PDF application, go to 'File', select 'Open', and browse for your interactive PDF form.
Click directly on the drop-down menus, checkboxes, or calculation fields. The advanced functions will now operate normally, allowing you to complete the document.

Redesign or Flatten the Document for Fill & Sign
If you are required to use Adobe Fill & Sign, the document must be converted into a simple, non-interactive flat form first.
Use WPS Office to Seamlessly Fill Interactive PDFs
Don't let limited applications break your workflow. WPS PDF provides robust support for interactive forms, recognizing checkboxes, drop-down menus, text fields, and basic calculations so you can fill out complex documents flawlessly.
- 1. Open your PDF form: Launch WPS Office, select the PDF tab, and open your interactive document.
- 2. Fill in the fields: Click on any interactive element, such as a drop-down list or text field, to input your data easily.
- 3. Save or Share: Once completed, click 'Save' to preserve the filled form data, or use the share feature to send it directly to recipients.

Frequently Asked Questions
Why do my drop-down lists disappear in Adobe Fill & Sign?
Adobe Fill & Sign is optimized for simple text overlays on flat documents. It intentionally strips out advanced interactive features like drop-down lists, calculation scripts, and interactive buttons because its engine does not support them.
How can I fill out a PDF form that requires automated calculations?
To utilize forms with automatic calculations or embedded JavaScript, you must open the document using a full-featured PDF application like WPS Office or Adobe Acrobat, rather than a basic mobile fill-and-sign app.
Can I convert an interactive form into a simple text form?
Yes. You can flatten an interactive form by opening it in a capable PDF viewer on your computer and choosing the 'Print to PDF' option. The resulting file will be a flat document devoid of interactive scripts, which can then be processed by basic filling tools.
