For our customer we need to split collection types by systems. We prepared some parent entities and all children are grouped by them.
It must to be user friendly solution so we want to modify te content manager menu and override collection types menu with our react code, where collection types will be grouped by parents.

In the strapi v3 there was custom admin feature and I was able to create '/admin/src/containers/HomePage/index.js` to override the home page. I cannot see similar option in v4 to override custom manger or inject some our code instead of menu. Injection zones work only for plugins but I need to override content editor menu. Is there any option to do that?

Best regards,

You can find all admin gui code for the content manager in here

My best guess would be that you could use patch package to change the package still there will be a cost of maintaining it with every strapi update.
