Proposal: Avoiding nested views with a merge tag (original) (raw)

But if I understand this tag correctly it will still create an instance of HBox? So this root tag will still create a container (which will be added as a Node to the displaylist), which may be unnecessary. Is it possible with this tag to not create a node in the displaylist, so that elements defined under the root tag are added to the container in which the fxml view is being used?

<fx:root xmlns:fx="http://javafx.com/fxml" type="HBox"> is good for?
