I'm looking for suggestions for the best way to implement a 'widget' to appear in a lightbox which can be called from a few different places. It's a currency converter so I'd like to be able to pass default values to it (2x currencies and 1x value). Once open I'd like it to be possible to change the currencies via a standard select drop-down box in a HTML form. The problem is I don't think lightboxes work very well with forms in my limited experience.
How would you guys approach this? Thanks in advance for any advice.
