I needed a hidden Gantry section so I could publish my Javascripts and modal code without creating a load of blanks space.

Solution

• Create a Gantry section called 'Hidden'
• Add the following CSS code to your custom.scss file

  /* Hide Hidden Section - So i can paste scripts into it without adding blank space */
  #g-hidden {
      height: 0px;
  }

So far it works but I have not extensively tested it.
