doesn't work with rails_admin_theme anymore

[arifikhsan]

Describe the bug I'm using rails 7. When installing rails_admin version 3 with rails_admin_theme, the theme doesn't work anymore. I cannot revert back to version 2 because it doesn't support rails 7.

Reproduction steps

1. make new rails project
2. install rails_admin
3. install rails_admin_theme and configure rollincode theme
4. see the dashboard with rollincode theme

Expected behavior I would expect to see something like this

but instead this is what I got

code is in here: https://github.com/arifikhsan/rails_admin_hello_again

Additional context

• rails version: 7
• rails_admin version: 3.0.0
• rails_admin npm package version: without nodejs. package.json is not exists
• full stack trace (if there's an exception): no exception

Add any other context about the problem here.

There are changes to themes in 3.0.0 that are likely breaking for themes (specifically, the update to Bootstrap 5), any downstream projects (ex. https://github.com/rollincode/rails_admin_theme) will need to update (though it looks like that project is now archived, not sure if there's a fork or alternative that would be viable)

In the meantime, you can remove the rails_admin_theme gem and stick with the default theme (and possibly do your own overrides), or downgrade rails/rails_admin to a version supported by rails_admin_theme.

Alternatively, you can downgrade your rails version if you'd like to use rails_admin 2.x.x with rails_admin_theme
