[development] Form altering in ajax

[Gordon Heydon]

Hi,

Take a look at the examples project, there is a couple of examples on how to dis this in D7, they are actually quite elegant, and usually only require a very few lines of code to do it.

http://drupal.org/project/examples

I think it is example 8,9 that show this.
