Hey guys,

it would be great to have a field formatter widget to render multiple values of a link field as dropbutton. I am talking about the front end output here.

Is there already any possibility to achieve this, apart from using views, where I would need to create and select multiple link fields for each option?

Thanks in advance for your help!

Version: 9.5.x-dev » 11.x-dev

Drupal core is moving towards using a “main” branch. As an interim step, a new 11.x branch has been opened, as Drupal.org infrastructure cannot currently fully support a branch named main. New developments and disruptive changes should now be targeted for the 11.x branch. For more information, see the Drupal core minor version schedule and the Allowed changes during the Drupal core release cycle.

Version: 11.x-dev » main

Drupal core is now using the main branch as the primary development branch. New developments and disruptive changes should now be targeted to the main branch.
