This open source and lightweight plugin allows users with the role Editor or Shop Manager to access the Menus and Widgets areas of the Appearance menu in WordPress’ admin area.
This is a common task that would be useful for clients to manage themselves to give them more control over their website’s content.
This plugin also gives access to the Customize submenu and other theme options, but these can be hidden through the options page at Appearance > Editor Access if you wish.
You can also select other menus to hide from Editors and Shop Managers (e.g. custom theme or plugin options pages), as well as hiding any elements on the Admin Bar.
