Expanding and collapsing sections of a form

I am creating a form in Adobe Acrobat which has several sections. Each section is it's own bookmark. (created automatically when I converted the form from MS Word) I am wondering if it is even possible to attach a toggle button to each bookmark heading and then using Javascript show or hide the individual sections (with the sections below it scooting up so there is no blank space). If you create a document in word this feature is built in using the headings function (a little triangle appears to the left of the heading and when you check or uncheck it the section is hidden and unhidden). I found a few things online that referred to Livecycle Designer, but was wondering if I am making this more complicated than it needs to be. (since this is a built in function in word.)?

Thanks,

Kenny
