JetFormBuilder media field, enhanced choose file

gistfile1.txt

UPDATED: 01.02.2025
1. We've enhanced the JetFormBuilder with a refined custom code, improving both style and functionality for file selection. The latest
update introduces support for the repeater field's media capabilities, offering a more streamlined and efficient user experience for
handling multiple files within forms.

2. Copy this code, create a new HTML snippet, and paste it into your snippet plugin. Save it as a header or footer.
