Me again, striving for functionality perfection

My test page:

I am hoping to always have at least one section of content open. Currently if you click on a section link you open that content, but if you click the same link again, it closes. Likewise if you have used the "expand all" function and then click on a section link, everything closes.

Any suggestions, ideas or code snippets . . . so that when you click a section link it will always open that section and close the others, irregardless of its current status . . . . and of course without effecting the function of the "expand all".

thanks!
