I have created a Node (AnchorPane) in the JavaFX scene builder and was wondering how to clone it.
I saw Duplicate/Clone Node in JavaFX 2.0
You can place the component that needs to be duplicated in a separate .fxml file.
Then you can load the separate file as many times as needed adding the nodes to the appropriate root in the main scene.
Additionally you can edit an element to the main .fxml file and include the separate .fxml file. You can then still work with it in the JavaFX Builder.
