When I'm editing my page i see all six of my navigation pages. I spent hours trying different themes, layouts and fonts to get it this way. I go to the preview and see the same navigation as i did in the editing mode. However, when i publish and go to my site instead of showing my contact us page it shows a "more" dropdown and in the drop is my contact us. Why does it do this and how do I fix it?!?!?
Being you didn't include a URL, I'm thinking this is responsiveness at play...
When you view your site, being it is responsive, the layout will respond to the width of the screen. With my test site, if I minimize the size of the window when viewing, the navigation automatically detects that and moves nav items into the More drop down so they are still available.
Try making your menu shorter. Example: Instead of "Contact Us" have it say "Contact". Instead of "Our Services", have it say "Services".
You get it?
