UI Builder

When you create a new UI Document (UXML) in the UI Builder, certain features are set by default:

• The UI Document is set to suit runtime UI.
• The UI Builder library only displays UI controls that are available for runtime UI.
• You can easily zoom in and out of the canvas of the Viewport window in UI Builder using your mouse wheel or trackpad.

To ensure that newly created documents are, by default, compatible with Editor UI and that the UI Builder library displays the additional controls for Editor UI, select Enable Editor Extension Authoring by Default. For more information, refer to Enable Editor Extension Authoring for UI Documents (UXML).

To disable zooming on your canvas using your mouse wheel or trackpad, select Disable Viewport Zooming via Mouse Wheel/Trackpad.
