Altering forms via server-side DOM manipulations should be documented in the 
book. It seems to come up a lot, but I don't think it's all that obvious or 
explicit in the book. The Views chapter (ch. 5) discusses HTML helpers and 
server-side DOM generally, but I don't think there's any discussion of using 
these methods specifically to customize forms (because FORM and SQLFORM are 
discussed in ch. 7, it's not immediately obvious that they are also HTML 
helper objects and can therefore be manipulated in the same way). Examples 
of this probably belong in the "Custom forms" section (
http://web2py.com/book/default/chapter/07#Custom-forms), or somewhere in ch. 
7.
