- Scenario
- Designing interactive PDF forms with custom button behaviors where a selected state must be visually maintained.
- Observed behavior
- Currently, the button only shows the colored icon while the mouse is held down and reverts to gray upon release. The desired behavior is for the colored icon to stay visible until the form is reset.
Ensure you have access to a PDF editor with form field creation capabilities, as standard push buttons do not natively support persistent toggle states without using a checkbox workaround or custom JavaScript.
Use a Checkbox Field with Custom Icons to Simulate a Toggle Button
Because standard push buttons don't hold active states, using a checkbox configured to look like a button is the most reliable way to maintain a pressed visual state.
A checkbox naturally maintains an 'on' and 'off' state. By customizing the appearance of a checkbox field to use custom icons, you can simulate a toggle button that stays pressed.
Open your PDF form editor, select the Checkbox tool, and draw the field where you want your toggle button.
Right-click the newly created Checkbox field and select 'Properties'.
Navigate to the Options tab. Look for the appearance settings or 'Icon' style. Set the 'Off' (unpressed) state to use your gray icon, and the 'On' (pressed) state to use your colored icon.
Create a separate 'Reset Form' push button. In its Actions tab, set it to reset the specific checkbox field so it returns to the 'Off' (gray) state when clicked.
Implement JavaScript to Toggle Button Icons
Write a custom script triggered on the 'Mouse Up' event to swap the button's appearance based on a stored state variable.

Frequently Asked Questions
Why does my PDF button revert to its original color when I release the mouse?
Standard push buttons in PDFs only reflect 'Up' (normal), 'Down' (pressed), and 'Rollover' (hover) states. They do not store a persistent state. To keep a button 'pressed', you must use a checkbox, a radio button, or custom JavaScript.
How do I make a reset button clear my toggle buttons?
Add a new push button to your form, go to its Actions properties, and select the 'Reset a form' action. Choose the specific fields (like your custom checkboxes or hidden fields) you want to revert to their default state.
Can I use my own images for the pressed and unpressed states?
Yes. When setting up a button or checkbox in a capable PDF editor, you can choose 'Icon only' in the appearance settings and upload custom image files (like a gray icon for 'Off' and a colored icon for 'On').
