Semantic Form Builder

Semantic Form Builder is a customer FormBuilder for use in Rails, aiming to give accessible, consistent, forms with the ultimate of DRY.

No more defining labels, worrying about formatting, etc. Let the default form_for tag take care of all the hassles for you

For an example of what it looks like check:


- script/plugin install git://
- rake semantic_form_builder:setup (if the installation script didn't move
the semantic_form.css into /public/stylesheets/)
  1. If you wish to use the builder to replace the default for all forms (which is great for consistency) then add the following into an initializer

    ActionView::Base.default_form_builder = SemanticFormBuilder

    Otherwise pass the builder in as the :builder parameter for form_for

  2. Be sure to include semantic_forms.css in your layout


Continue using form_for and the tag helpers within it as you did before and it should work fine. There has been a few additional tags added for convenience sake. They are:

- submit_and_cancel
- radio_button_group
- check_box_group

More documentation on their usage to come, in the interim check out or the following example:

<% form_for @document do |f|

field_set_tag "Form Details" do %>
  <%= f.date_select :date, :required => true, :help => "date the something happened" %>
  <%= f.text_field :number, :required => true, :help => "the reference number for this thing" %>
  <%= :external_id, [["Choose an option...",""]] +{|c| [,]}, :required => true, :label => "options", :help => "select something from the list" %>
  <%= check_box_tag_group "document[other_items][]",{|u| { :value =>, :label => u.description }}, :label => "including these?", :help => "tick the whatever boxes are appropriate for this&nbsp;thing" %>
  <%= f.text_field :name, :help => "what was Willis talkin' about?" %>
  <%= f.check_box :list, :label => "mailing list", :help => "can we send you a bunch of spam?" %>
  <%= f.submit_and_cancel("save", "cancel") %>

<% end %>
