Currently, the element from which a widget is initialized is wrapped in an additional parent element in some cases ("Editors" widgets for example). I would like to have the possibility to add an id to the parent as this way styling the widget will be much easier. 

For example, with the current implementation of the TextArea I need to use specific CSS selectors to style the component (Dojo). It will be much easier if there is an option to add an id to the wrapping parent.
