To change the order of your pages and to show or hide them you need to go to Step 3 webpages and click on the organise pages button.
The page you see is split into 2 columns. The columns on the left represent every page group and item on your website. To organise your pages you drag accross a copy the pages etc and order them how you want them to be shown on your website.
If you don't want a page to be shown then do not drag it accross to the right. If you have a page showing that you want to hide simply click once to highlight it and press remove. The page will be removed from the right but will still be visable to the left so you can reinstate it at a later date should you wish.
We hope this is helpful,
