Cannot create DropdownField with nested choices when using UIToolkit

Unity: UI Toolkit Controls

Won't Fix

2023.3.X

2023.2.X

2023.2.0a15 onwards

Contextual Menus were recently reverted from 2023.3.X, therefore the issue is now non-repro in this editor version. Port canceled.

Due to the state of the new Contextual Menus feature, we decided to revert to OS Menus in 2023.3. Hence, we are cancelling all 2023.2.X ports and recommend using 2023.3.0b1 or higher for more stable context menus. The feature will be reconsidered in future versions.

How to reproduce:
1. Open the attached project "DropdownIssue.rar"
2. Open Window>UI Toolkit>Test Dropdown with Nested Choices
3. Click on any dropdown in the "TestDropdownView" window

Expected results: The choices are nested
Actual results: The choices are not nested

Reproducible with: 2023.2.0a15, 2023.2.4f1, 2023.3.0a18
Not reproducible with: 2022.3.15f1, 2023.2.0a14
Could not test with: 2021.3.33f1 (compilation errors in the Console window)

Reproducible on: Windows 11 22H2
Not reproducible on: No other environment tested
