Demo of a popup that repositions itself if there are form errors
On a desktop or wide display, you should see a popup with a Gravity Forms form inside it. The popup will not launch on mobile displays.
Click on the SUBMIT button without any of the fields filled-in to generate errors.
The popup will automatically reposition itself so that the error messages don’t push the lower part of the form out of the displayable area.
See the source code that fixes the issue on GitHub.
