带引导程序的内联下拉形式

Question

我正在尝试使用twitter bootstrap创建内联表单。当我执行以下操作时，文本字段都是内联的，但下拉按钮不是。相反，下拉按钮与屏幕一样宽。我怎样才能使它内联？

      

    <%= form_for @project, {:class => "form-inline"} do |f| %>
      <%= render 'shared/error_messages', :object => f.object %>

      <%= f.text_field :a, :class=> "input-small", :placeholder=>"a" %>

      <%= f.text_field :b, :class=> "input-small", :placeholder=>"b" %>

      <%= f.text_field :c, :class=> "input-small", :placeholder=>"c" %>

      <%= f.text_field :d, :class=> "input-small", :placeholder=>"d" %>

      <%= f.text_field :e, :class=> "input-small", :placeholder=>"e" %>

      <%= f.label :one_two %>
      <%= f.select :one_two, options_for_select([['One','One'],['Two',Two]]) %>

      <%= f.submit "Submit", :class => "btn"  %>
    <% end %>
  </div>
</div>

也许你可以尝试以下方法来包装select标签。

<div class="control-group">
            <label class="control-label"><%= f.label :one_two %></label>
            <div class="controls">                 
                 <%= f.select :one_two, options_for_select([['One','One'],['Two',Two]]) %>
            </div>
</div>
