Hi all

I’d like to group my fields on a form into visual separate areas. My  
plan is to surround fields that belong together with fieldset/legend  
tags:

 Personal Information form.text\_field :name form.text\_field :email Additional Information form.text\_field :xxx form.text\_field :yyy

I’d like to add a helper method to the form builder that creates this  
fieldset/legend tag pair:

\<% form.visual\_group(‘Personal Information’).do %\>  
form.text\_field :name  
form.text\_field :email  
\<% end %\>

\<% form.visual\_group(‘Additional Information’).do %\>  
form.text\_field :xxx  
form.text\_field :yyy  
\<% end %\>

I’ve come so far with my poor Ruby knowledge:

def bla(caption)  
“#{caption}#{yield}”  
end

Sadly this does not really work - the fieldset/legend tags are not  
written to the template…

How can I achieve this behavior? 🙂 Thanks  
Josh

I haven’t time to check what you misses, but for obtaining the same  
result, I use the following helper method:

def fieldset\_tag(legend, options = {}, &block)  
concat(content\_tag(‘fieldset’, content\_tag(‘legend’,legend) +  
capture(&block), options), block.binding)  
end

Thank you, but I get the following error:

undefined method `capture’ for #IncenseFormBuilder:0x2368898

The method was intented to be used as

\<% fieldset\_tag(‘Personal Information’) do %\>  
\<%= form.text\_field :name %\>  
\<%= form.text\_field :email %\>  
\<% end %\>

You can put code in app/helpers/application\_helper.rb

If you, instead, want to include it into your formbuilder, then, try to  
include all modules needed (like include  
ActionView::Helpers::CaptureHelper, for capture method; see API)
