Thanks for that. Yes, I do have the Xtreme theme support plugin.
So are you saying that I can put 2 widgets or columns in my home page, then move the menu/content section into one of those columns or widgets and it will work the same as it does currently at the top of the page under the image, similarly to this site: http://www.isabelallende.com/en/home ?
Also one other problem [sorry!]. on mobile phones, when tapping ‘menu’ on my site, it comes up showing all pages in a list instead of showing them like on the website, where you have menu items with sub-menus under them. For example, on my website on computer, under ‘books’, you can then go to one of 2 books, and from there choose ‘summary’, ‘excerpt’ etc. But on mobile phone, all of these are just on one list so you end up with 2 summaries, 2 excerpts etc, without knowing which belongs to which. How can I fix this so that contents look the same as on the computer? Here’s a pic of how it looks on phones:
