One of the first web apps I worked on back in 1997 was a BT ordering system for ISDN-30 installations. The original specification of the form on which one configured the various options of the thirty lines needed about 300 checkboxes, but that was impossible on 16-bit Windows - the browser (whether Netscape Navigator 3 or IE3) would simply leave a third of the form empty, or possibly crash if you were trying to do something weird like run Word at the same time.
In the end I redesigned it to allow five different configurations allocated to ranges of lines, on the basis that 90% of the time all thirty lines were configured the same way, and there were seldom more than two or three different configurations for any given installation. If people needed any more options than that they could say so in the "Additional Information" box, and somebody at BT would have to phone them to get the details
