Gravity Forms only shows up on child site when created by user with Admin role

By default Gravity Forms is only visible in the admin by administrators. This is standard practice for any plugins that have an admin interface because typically you only want the admin to have access to the admin tools.

If you want any role other than the Administrator to have access you would either have to use a plugin such as the Members plugin to add the appropriate capabilities to that role, or you could write some custom code to do this if you don't want to use a plugin to handle it for you.

Here are two forum posts that discuss doing this without a plugin:
