Description

Bug Description:

Hi, I am using the Tree View as a vscode extension, and I set the options canSelectMany and showCollapseAll to true in the vscode.window.createTreeView() API, but it does not have an effect in Theia.

Additional Information

  • Operating System: Windows 10
  • Theia Version: 1.16

Contributor guide

Research direction
Inspect the tree view widget implementation to verify if the `showCollapseAll` option is passed correctly from the API to the widget, and check if the collapse all button is rendered conditionally based on that option.
