hide donation form menu item

I know I could have inserted the donation form into content, but tried that and had formatting and module alignment issues. It turned out to be easier to create a menu item for the donation form.

What I want to be able to do is actually hide the menu item because I want site visitors to arrive at the donation form from a link on a different page.

There should be a simple way to do this, I just don't know how!

Thank you for any help.
