i have created a custom formbuilder …

class Std\_Form\_Builder \< ActionView::Helpers::FormBuilder

def self.create\_field(method\_name)  
define\_method(method\_name) do |label, \*args|  
@template.content\_tag(‘div’,  
@template.content\_tag(‘div’,  
@template.content\_tag(‘label’, label.to\_s.humanize + ‘:’,  
:for =\> “#{@object\_name}\_#{label}”),  
:class =\> ‘fLabel’) +  
@template.content\_tag(‘div’, super, :class =\> ‘fField’),  
:class =\> ‘fRow’)  
end  
end

field\_helpers.each do |name|  
create\_field(name)  
end

end

what i want to achieve is that all the field\_helpers get populated with  
a default css class. i have no clue … it should still be possible to  
override the css class if necessary.  
thx for help
