Thank you for opening this issue @kzimins-arvatosystems 🙏
It is our oversight. 🙈
For any rgba calls only <color>Channel can be used.

It seems to be an issue with the use of RGB variables. The format for RGB in CSS variables should be three comma-separated numbers, representing the red, green, and blue channels (values ranging from 0 to 255), such as 0, 72, 118.
ex:

rgb(var(--dc01-rgb) / 0.15) is valid

@LukasTy Hi!

After today's release, I'm still experiencing issues with styles. rgba(hex / opacity) and rgba(rgb / opacity) doesn't seem to be valid syntax, probably must be rgb, so right syntax may be:

Also, TreeItem2DragAndDropOverlay is not exported from the pro package. I'm importing everything else from the pro package, so could this be the cause of the issue?

Hello @kzimins-arvatosystems
I'm sorry to hear you are still experiencing issues with this. 🙈
That's my bad, I applied the fix on the master branch but forgot to cherry-pick it to the current stable release.
Is it blocking you, or can you wait for the next release this Thursday? 🤔

It is re-exported from @mui/x-tree-view-pro root. We do not re-create the folder structure on the commercial packages to re-export files from community package with the same path.
The import path shouldn't change anything, but feel free to import it from the pro package with the following line:

import { TreeItem2DragAndDropOverlay } from '@mui/x-tree-view-pro';

No problem, I can wait, thanks for the reply!

Once again, I'm sorry for causing confusion in this transition state, where we are preparing the master branch for v8.
The renamed TreeItemDragAndDropOverlay is exported from @mui/x-tree-view-pro:

mui-x/packages/x-tree-view-pro/src/index.ts

Line 11 in 4c6b35f

export * from '@mui/x-tree-view/TreeItemDragAndDropOverlay';

@flaviendelangle have we forgotten to export TreeItem2DrangAndDropOverlay from the pro package?
Should we fix it for v7? 🤔

[flaviendelangle]

Sure
We need to fix 1-2 things regarding doc gen but it's totally doable

Will you take up this effort?
Or should I do it?

[flaviendelangle]

I can take care of it if you want
