- Observed behavior

Adjust Button Field Properties to Remove the Border
Change the appearance settings of the button field to eliminate the gray outline entirely.
In PDF editors like Adobe Acrobat, form fields often have a default border applied to make them visible to users. You can easily hide this border by setting its color to 'No Color' in the field properties.
Open your PDF document in your PDF editor and activate the 'Prepare Form' or 'Edit Form' mode from the tools menu.
Right-click on the specific empty button field displaying the gray border and select 'Properties' from the context menu.
In the Button Properties dialog box, click on the 'Appearance' tab to access the visual settings for the field.
Locate the 'Border Color' option and change the selection to 'No Color' or transparent. You can also ensure the line style is set properly.
Click 'Close' to save the property changes, then switch to the preview mode to verify that the gray outline is no longer visible.

Frequently Asked Questions
Why is there a default gray border around my PDF form fields?
PDF editors often apply a default gray or light-colored border to form fields so users can easily identify where they need to click or type. This is purely a visual aid and can be hidden in the field's appearance properties.
Can I remove the border but still keep the button functional?
Yes, changing the border color to 'No Color' only affects the visual appearance of the button. The button's actions, embedded scripts, and overall functionality will remain completely intact.
How do I hide the blue form field highlighting when viewing a PDF?
In most PDF readers, you can turn off the form field highlight feature by going to Preferences > Forms and unchecking the 'Show border hover color for fields' or 'Highlight fields' option. Note that this only changes your local viewing experience.
