Does not work on default Drupal 9.4 Admin Theme - Claro

The fact is Claro table structure is different than expected by required_field_display module.

One solution is to rewrite required_field_display code to target Claro's structure (keeping existing code as it works for others admin themes).

Other solution is to add some CSS:

#block-claro-content .form-required .tabledrag-cell-content__item::after {
	content: '*';
	color: #e32700;
	margin-left: 4px;
}

If you're already using a child theme of Claro as your admin theme or a custom module, you can add the above lines to your css (which will do nothing in a custom front theme because we're in the admin space).
If not, attached patch will add these lines to required_field_display module as a temporary fix.

BTW, I'm not sure about the best solution nor about which of Claro or required_field_display should be modified...

It doesn't work with Olivero theme as well. So, adding #block-claro-content theme-related selector is not correct.

Created a new MR.

Implemented it in the following way:
- added a new custom wrapper to the 'Manage form display' form and 'Manage fields' table;
- added an additional class to cells with required fields (.required-field);
- created a new library with styles for required fields;
- attached the library to both the form and table.

Tested with all default themes for D10 themes (Olivero, Claro, Stark) and some contrib themes (Barrio Bootstrap 5, Bootstrap 5 admin).

Hi @Aston Victor,

I hope you are doing well. I reviewed and tested MR7 on my Drupal 9.4.0 setup, and the patch applied cleanly. Before applying the patch, the required fields were not showing on the manage field in the Claro theme. However, after applying the patch, it successfully resolved the issue, and now the required fields are visible in the manage fields section. I'm attaching screenshots for reference.
Moving it to RTBC.

Thanks for your work on this.

Thanks for the review.

Merged and will be released in the next version.
