Node Bar/Node Palette Missing

[battle1217]

Hi! I'm working on a substance graph.

All of a sudden, my node bar or node palette (whatever the name is) is missing from the window. 

A.PNG is the current toolbar and B is the original toolbar. 

How can I bring back all the node icons to the toolbar? 

Thank you in advance!

Hello! 

The node palette is toggled using this button in the toolbar:

Best regards.

Thank you so much! I was Googling about this and couldn't find the solution.
