Click to select the node component you wish to put ahead of another.
Go to the Level buttons in the node component
toolbox. Click on the arrow and select how many levels you want to move the
selected component up or down (you can see that the selected component is
marked with the blue background in the list of components).
In this example, we click one level up, to put the selected text in front of the picture.
The selected component is now in front of the picture.
