Form Generation Library - Printable Version

Code:

// my suggestion of a prefix/suffix implementation

// i'm not a fan of a per element configuration and 

// rather would have a global configuration of:

//

// element prefix/suffix

// fieldset prefix/suffix

// label prefix/suffix

// input prefix/suffix

//

// and then turn it off for specific elements with a

// last accessed method like ->nowrap() or something like that

&lt;form&gt;
