Here is a scenerio that could clearify my question. A user wants to update card but instead of jumping to another page to verify the available colors,size and prizes of product, those information are shown in a floating window and changes in the floating window can affect the underlying one.
My question is : 1. What are some of the approaches to encounter this situation? 2. Are there any helpful tips, tricks and links on this subject?
I am comfortable with js,php and zend. I would appreciate any advice,tip and tricks, problem solving approach to handle a situation like this! Thanks in advance. Hope this make sense.
