Can I use this plugin for elements in a repetitive group?
Hello @gonzalolluch,
Thank you for reaching out to us!
Yes, you can definitely use the Mouse & Element Positions plugin with a Repeating Group. Simply use the “Current cell index” in the attribute ID to ensure the element functions only for the current cell.
For a simple example, check out this test page: zeroqode-demo-10 | Bubble Editor
If you have any further questions or need some assitance, please let me know. 
Thank you again, and I look forward to hearing from you soon.
Best regards,
Stefan
