draggable: cssNamespace option should be removed, addClasses option added
|Reported by:||rdworth||Owned by:|
Per team discussion on
the draggable option 'cssNamespace' should be removed (not deprecated). This option had two intents
- Allowing for customizing the 'ui-' prefix of all UI css class names added to draggable elements. This is not compatible with the jQuery UI CSS Framework and is not intended for support by the team.
- Preventing the .addClass("ui-draggable") on many hundreds of elements at init for performance reasons, by setting cssNamespace option to false. Per the same discussion, this should instead be implemented as a new option 'addClasses' with a default value of true.
