If you want to hide a page from the navigation menu:
(1) In v1.5.0 or later...
On the 'Pages' tab, drag and drop the page onto the 'Hidden pages' text.
(2) In versions prior to v1.5.0...
Edit the page and deselect the 'Show in Nav' checkbox.
You need to have one page/link visible in your menu as your home page.
If you want to hide the entire navigation menu, then you will need to do this using CSS.
Add the following CSS to your theme's 'custom.css' file.
For example, if you are using the Kosel theme, then the file will be located here: 'showkase/_themes/kosel/css/custom.css'.
nav#nav {
visibility: hidden;
}
