The choices will be quite simple so I might just do this manually with a structure of pages. It’s a shame there isn’t a nice widget way of doing it though. I’ll let you know if I find anything!
I set a static page as the front page in the site settings, then went to said page and took the tick out of ‘include this page…’ in the page’s settings.
I appreciate that unordered lists can run horizontal (rather than vertical)using CSS but how does one use CSS to call up thumbnails for the child pages if one wishes them to be sourced from the featured images set on pages?
