RSD - How do I create expand/collapse...
am currently evaluating RSD (Responsive Site Design), and while I am actually recreating a web site, I would like to know how does one create an expand/collapse against either button link or text link, rather than referring to a new web page, as this would be a lot easier when one is using the mobile phone. I have looked at FAQ and Community web page, but can't see a reference to what I am actually trying to achieve, so any help here would be appreciated.

An 'expand an collapse' what? Do you mean a menu, a so-called 'hamburger' menu? Or an accordion? Take a look at my sharing folder (url in signature) and see if you find something like what you are thinking of. There are a number of menus, and there is also an accordion down at the right bottom.
