Remarks

TwRadioGroup provides two ways to use radio groups:

1. Manual: Add TwRadioButton components as children (ChildContent)
2. Automatic: Provide Items and bind to Value for automatic radio button generation Radio buttons within the group should share the same Name parameter to form a mutually exclusive group. The group can be oriented horizontally or vertically, and supports customizable spacing. The component supports cascading the Name to child radio buttons.
