Ninja Forms Auto Email Copy - jQuery Solution

This jQuery script automatically copies an email address from one field to multiple other fields when a checkbox is checked. Perfect for forms where users want to use their business email for multiple purposes (billing, support, marketing, etc.).

Features

• ✅ Copy email from main field to multiple target fields
• ✅ Real-time updates when main email changes
• ✅ Fields remain editable for user overrides
• ✅ Clears target fields when checkbox is unchecked
• ✅ Waits for DOM elements to load properly

This snippet detects values like "'+441234..." added by CSV-escaping and removes the leading apostrophe only when the rest of the value matches a reasonable phone pattern.
