Want to get rid or BIG webpage

Hey.
I have a webpage with 52 textboxes on it and it the requirement.
But by doing so it has made my web page very big and i have to srcoll right and sometime down to fill the fields.
is there any way that i coudl hide some of the fields on one click while having them on same page.
and when user want them he may be able to click back on the same label or whatever and it comes visible...

Thanks

group them in block with <DIV> tag and set them visible/hidden on click of some link/button
