PR Summary

• Added auto-add feature and improved UI for Custom Fields
  Users can now automatically add an existing fieldset when creating or editing a new field. Fieldsets are displayed in a sidebar on small and medium screens, improving the layout consistency with other pages. Fixed a bug related to selecting all fieldsets.

• Enhanced field syncing on new fieldsets
  When adding or editing fields, the system now syncs selected fieldsets with their respective ids, removing unselected ones from the pivot table.

• Improved Custom Field usability
  The custom field delete button is now disabled when the field has a related set, preventing potential issues.

• Added tests for CustomField::format() method
  Testing ensures the method returns the expected value based on its input parameter (IP, URL, or Email).

This...I like this.... 👍🏾

Side-note: since $fields is a collection you could skip the foreach and do

Suggested change

	if ($fields->count() > 0) {
	foreach ($fields as $field) {
	$field_ids[] = $field->id;
	}
	$fieldset->fields()->sync($field_ids);
	}
	if ($fields->count() > 0) {
	$fieldset->fields()->sync($fields->pluck('id'));
	}

Are we sure what will work as expected - it feels to me more like it would only associate that one it's syncing to, unsyncing the others (which is why I set it up as an array).

[marcusmoore]

I think it would be ok. $fields->pluck('id') will return a collection of the ids, which can be cast to an array, in the same way $field_ids[] is formatted.

Definitely don't hold up the PR for this comment though 😄
