#42 is applied correctly in 9.5.3 and in my opinion works as expected.

Thanks for providing this solution.

Tried testing #42 with v3.3.0 on Drupal 10.1.x-dev.
On applying patch, getting below:

Skipped patch 'css/admin.toolbar.css'.
Skipped patch 'js/admin_toolbar.hoverintent.js'.

Rerolled #40 for the v3.3.1 - 3.x-dev 50ff7eb6 commit. Tested with Drupal 9.5.8.

Tried to apply patch #46 it is working fine for add content menu but not working properly for last content type in content type list for content type I have shared video.
need to work on it.

We've changed a little bit the patch so it can apply to Claro but also to Gin and works a little better with submenus as shown in #47 video.

We haven't tested yet on RTL theme and also the vertical admin menu bar for Gin is not functional, so keeping status as Need work.

patch #46 works for me in drupal 9.4.10 Panopoly thank you.

Patch #46 could not be applied in admin_toolbar 3.4.1 and drupal 9.5.10.
Instead #48 was applied correctly and seems to work correctly.

#48 works well for us on Drupal 10.1.3 and Admin Toolbar 3.4.1

Indranil Roy → made their first commit to this issue’s fork.

I have just made a couple of theming changes based on #48 to improve the appearance. Using Claro theme and Drupal 9.5.11.

I rerolled patch #48 for Admin Toolbar 3.5.0 on Drupal 10.3.1
