Is there a way to crop a node?

Hi it’s my first post here. I was looking for that answer in a google, but no luck.

Basically I’ve got node that is to wide and it bugs me off. When you zoom out far enough it crops itself but only for a preview. So if I would like to add some more nodes I would have to go all the way to the end of that node which is ridiculous.

Is there a way to crop/size it down?

Thanks in advance!
