You can change the view of your websites tabs from across the page to down the page. For example see below:
To do this:
1. Go into 'Site Builder' within 'Website Management'. To the left hand side you will have your pages.
2. To change the order of the pages on your site, you simply drag and drop a page either above or below another.
3. If your site has 2 or more pages you will be able to to put one of the page tabs under another. To do this, you click on the lower page and push it inwards of the screen (left to right).
The Site Builder automatically saves any changes. When on your site, hovering over a main page tab, the other pages will show up underneath.
