I have a desktop app written in WinForms that displays sets of nested data in a TreeView with columns aka TreeList (data is folders and files with columns for sizes and some custom parameters). I am writing new crosplatform app with Avalonia and looking for a way to do the same but all I see is simple TreeView and GridView\DataGrid.

My main goal is to have a way to browse and select nested data in a dialog that returns list of selected data to work with further. But I also need to see some parameters of that data.

Is there a way to implement TreeList or maybe there is some analog to display a tree and data associated with its nodes at the same time?

There is a TreeDataGrid that you could be potentially interested in, but the project status for today is defined as "early beta", so it might contain some bugs:
