I need to click on a link in my site and have a window over lay the screen line in a lightbox were the rest of the screen goes dark/grey. The content in this box, dialog/lightbox needs to come from an iframe. I need to be able to stay with in the iframe till the search is done and and the 2nd page it loads is complete then have a button that allows me to close the query over lay.
How is this done? I need help with this step by step.
