I have a page with a navigation column and a data column that I wish to control separately, both sides use forms. When I scroll down and click on a button on navigation side I want the data side to change accordingly but I want the nav side to stay put (no repositioning).
My first two thoughts is frames or separate windows -- either is fine for me. But how can I control the data side from the nav side? Can I send a PHP script command to another frame/window or can PHP only affect the current window?
