Configurations off-canvas: link to trigger off-canvas

@royalpinto007 Thanks for your contribution to Paragraphs Gridstack.

I didn't add a good description for this task, so probably you didn't understand the idea of the task.
Also, this issue is already assigned to another contributor and this is a bad tone to work on assigned tasks.

The first problem with your MR is using a 'field_children' field name to get a child paragraphs, but this is a paragraph behavior plugin and it could be applied to any type of paragraph.

  // Attach ajaxified link to gridstack container children.
  $children = $paragraph->get('field_children');

The second problem is using 'entity.node.canonical' for generating a Link to the paragraph. Also, the setOptions() method is not applicable to the Link object. It works only for a URL object.

  // Create a link for the child entity.
  $link = Link::createFromRoute($child_entity->label(), 'entity.node.canonical', ['node' => $child_entity->id()]);

  // Ajaxify the link.
  $link->setOptions([
    'attributes' => [
      'class' => ['use-ajax'],
      'data-dialog-type' => 'modal',
    ],
  ]);

And the last piece of code that doesn't work:

  // Attach the link to the child entity.
  $child_entity->link = $link;

@royalpinto007 How did you write this code? Did you use some kind of AI e.g. ChatGPT?
