Alternative to fancybox?

The site I am working on was using a fancybox to display checkboxes and such so that an admin can easily add more items to a specific product. After messing with it for way too long, I have to scrap that fancybox, but now that the page is broken, I'm not sure what to do. The checkboxes that were displayed are in such a large quantity that using collapsible divs would just make the page a huge mess.

I开发者_运维知识库s there a different modal pop-up that might work better than fancybox? I read that modals just don't work with ASP and that is what I am using for this site. ASP.net 4.0 using VB. If anyone has ideas or suggestions I would love to hear them. I'm struggling with where to take this project now.

There are hundreds of jQuery plugins with modal windows and close functionality. For example check this . I personally use colorbox
