[Lift] Re: Customizing generated form elements without touching scala code

[Marius]

I disagree with the unglyness you are talking about just because
Snipets are UI elements. However you can preserve the attributes from
the markup such as:

def doit(xhtml: NodeSeq): NodeSeq = {

  bind(f, xhtml,
text -% SHtml.text(name, println _)
  )

}


and in the markup


lift:MySnippet.doit
   f:text class=abc size=3/
/lift:MySnippet.doit

 Hi,

 I'm trying to get my first form in Lift running and I'm having the
 following problem:

 I use for example SHtml.text(..) to create a text input element.
 Unfortunately, this element has no specific class or id such that I can
 customize it using CSS or whatever.

 I know that I can add some parameters to SHtml.text(..) which are passed
 to the generated form element but this means that I have style
 information in my scala code. And this is, in my opinion, very ugly.

 Is there a better solution?

 I could imagine something like e:myfield class=somecssclass/. This
 class information is accessible in scala so the form generator could
 automatically add it to the generated element...

 Thanks in advance for your help!!

 Julian

Thank you for your answer, also thanks to Jeppe who posted the same 
solution.

I already read that and although I don't want to start a discussion on 
this, I want to share my opinion with you:
I already read in some blog entries and also here on the mailing list 
that lift completely avoids the problem of having business logic in your 
views/templates.
I think in general, this is a very good idea. On the other hand, many 
people say snippets are part of the view. In almost all examples I 
found, you can see business logic in the snippets. Is this really better 
now? I think you are still mixing business logic and UI stuff, just on a 
different level. Of course, you can seperate that but this adds 
unnecessary complexity to an application.
Or am I missing something? I'm still a beginner in the scala/lift 
world... :-)
