How to clone Trix default link button, so I have modal and insert text into editor?

[cimenta]

Hi

I need help because after extensive Google search I did not find any solution.

I would like to add a button to Trix editor that would insert YouTube video using custom HTML attribute. It seems to me that default link button is exactly what I need. I would need to just modify little bit what is done once someone click the link button after text is entered.

The standard link button

• has Trix menu button
• has input field
• has input value validation
• link and unlink functionality. I might want to remove the unlink button
• inserts text into editor

I was searching the net but did not find any example how to achieve what I want. The closest solution is https://www.kindleman.com.au/blog/advanced-actiontext-modifications-for-cms-use/ the embed, image, and link buttons are basically what I want. But it is coded in RoR. I know nothing about RoR.

Could someone help me to create my link (embed) button in Trix?

Thank you
