Rails helpers for Bootstrap styled fields. I use these in conjunction with simple_form to provide non model fields.

bootstrap_helper.rb

module BootstrapHelper
  def bootstrap_best_in_place_if(condition, object, field, options = {})
    content_tag(:div, class: "control-group string optional #{options.delete(:wrapper_class)}".strip) do
      label_tag(field, options.delete(:label), class: 'string optional control-label') +
      content_tag(:div, class: 'controls') do
        best_in_place_if condition, object, field, options
      end
    end
  end

  def bootstrap_check_box_tag(field, value = "1", checked = false, options = {})
    content_tag(:div, class: "control-group boolean optional #{options.delete(:wrapper_class)}".strip) do
      label_tag(field, options.delete(:label), class: 'boolean optional control-label') +
      content_tag(:div, class: 'controls') do
        hidden_field_tag(field, 0) +
        label_tag(nil, nil, class: 'checkbox') do
          check_box_tag field, value, checked, options
        end
      end
    end
  end

  def bootstrap_collection_select(object, method, collection, value_method, text_method, options = {}, html_options = {})
    content_tag(:div, class: "control-group select optional #{html_options.delete(:wrapper_class)}".strip) do
      label_tag(method, options.delete(:label), class: 'select optional control-label') +
      content_tag(:div, class: 'controls') do
        collection_select(object, method, collection, value_method, text_method, options, html_options)
      end
    end
  end

  def bootstrap_select(object, method, choices, options = {}, html_options = {})
    content_tag(:div, class: "control-group select optional #{html_options.delete(:wrapper_class)}".strip) do
      label_tag(method, options.delete(:label), class: 'select optional control-label') +
      content_tag(:div, class: 'controls') do
        select(object, method, choices, options, html_options) +
        (html_options[:hint] ? content_tag(:p, html_options[:hint], class: 'help-block') : '')
      end
    end
  end

  def bootstrap_select_tag(name, option_tags = nil, options = {})
    content_tag(:div, class: "control-group select optional #{options.delete(:wrapper_class)}".strip, id: options.delete(:wrapper_id)) do
      label_tag(name, options.delete(:label), class: 'select optional control-label') +
      content_tag(:div, class: 'controls') do
        select_tag(name, option_tags, options) +
        (options[:hint] ? content_tag(:p, options[:hint], class: 'help-block') : '')
      end
    end
  end

  def bootstrap_text_field_tag(field, value = nil, options = {})
    content_tag(:div, class: "control-group string optional #{options.delete(:wrapper_class)}".strip) do
      label = label_tag(field, options.delete(:label), class: 'string optional control-label')
      if options[:datepicker] || options[:class] && options[:class] =~ /datepicker/ || value.class.name =~ /Date|Time/
        options[:class].gsub!(/datepicker/,'') if options[:class]
        label + content_tag(:div, class: 'controls input-append datepicker') do
          text_field_tag(field, value, options) +
          "<span class='add-on'><i class='icon-calendar'></i></span>".html_safe
        end
      else
        label + content_tag(:div, class: 'controls') do
          text_field_tag field, value, options
        end
      end
    end
  end

  def bootstrap_datepicker_tag(field, value = nil, options = {})
    content_tag(:div, class: "input-append datepicker #{options.delete(:wrapper_class)}".strip) do
      text_field_tag(field, value, options) +
      "<span class='add-on'><i class='icon-calendar'></i></span>".html_safe
    end
  end

  def bootstrap_text_area_tag(field, content = nil, options = {})
    content_tag(:div, class: "control-group text optional #{options.delete(:wrapper_class)}".strip) do
      label_tag(field, options.delete(:label), class: 'text optional control-label') +
      content_tag(:div, class: 'controls') do
        text_area_tag field, content, options
      end
    end
  end
