I would like a user that is NOT a super admin, but a admin, to have the rights to add <scripts> and <style> to a page. I do not want to give him super admin rights. But without being a super admin, he cannot add a <script></script> to a page, so my menu breaks.
What rights do I give him? He has all of the “themes” rights, but I am not able to figure out what checkbox to check.
1st, decide if you trust this person enough. Using script tags may lead to the permissions compromising and vulnerable.
2nd, go to the “Network Admin -> Settings -> User Role Editor -> Multisite” tab and turn ON the Enable "unfiltered_html" capability option.
3rd, go to the site where you user has ‘administrator’ role and open ‘Users->User Role Editor’, select ‘administrator’ role, turn ON the ‘unfiltered_html’ capability. It’s located at the ‘Deprecated’ group.
