twitter bootstrap 折叠第一项并在加载时打开第二项

Question

我是第一次使用 twitter boostrap，并且正在使用折叠式手风琴。

当页面加载时，默认打开第一个项目，其余项目全部折叠。

我希望在页面加载时默认打开第二个项目并默认折叠第一个项目和其余项目。

有没有简单的方法来实现这一点？我尝试过使用 data-toggle 属性，但没有得到任何结果。

<div class="accordion" id="accordion2">
  <div class="accordion-group">
    <div class="accordion-heading">
      <a class="accordion-toggle" data-toggle="collapse" data-parent="#accordion2" href="#collapseOne">
        Name &amp; Location
      </a>
    </div>
    <div id="collapseOne" class="accordion-body collapse in">
      <div class="accordion-inner">
        <%= f.input :name %> <br/>

        <%= f.input :addr_1, label: 'Address' %> <br/>

        <%= f.input :addr_2, label: false %> <br/>

        <%= f.input :addr_3, label: false, placeholder: "County, State, Provence, Region etc" %> <br/>

        <%= f.input :country, label: false, :priority => [ "Ireland", "United Kingdom" ] %>  <br/>

        </div>
    </div>
  </div>

    <div class="accordion-group">
    <div class="accordion-heading">
      <a class="accordion-toggle" data-toggle="collapse" data-parent="#accordion2" href="#collapseTwo">
        Description
      </a>
    </div>
    <div id="collapseTwo" class="accordion-body collapse">
      <div class="accordion-inner">

        <%= f.input :description, :input_html => { :cols => 10, :rows => 3 } %> <br/>

        <%= f.input :looped, :as => :boolean %> 

        <%= f.input :duration_hours, :label => 'Duration',  :collection => 0..12, :include_blank => false, :hint => "hours" %>

        <%= f.input :duration_mins, collection: [ 0, 15, 30, 45 ], :include_blank => false, label: false, :hint => "mins" %>
      </div>
    </div>
  </div>


  <div class="accordion-group">
    <div class="accordion-heading">
      <a class="accordion-toggle" data-toggle="collapse" data-parent="#accordion2" href="#collapseThree">
        Images
      </a>
    </div>
    <div id="collapseThree" class="accordion-body collapse">
      <div class="accordion-inner">
        <%= f.simple_fields_for :photos do |builder| %>
          <%= render 'photo_fields', f: builder %>
        <% end %>
        <div style=clear:both;> </div>
        <%= link_to_add_fields "Add More", f, :photos %>
      </div>
    </div>
  </div>

  <div class="accordion-group">
    <div class="accordion-heading">
      <a class="accordion-toggle" data-toggle="collapse" data-parent="#accordion2" href="#collapseFour">
        Route
      </a>
    </div>
    <div id="collapseFour" class="accordion-body collapse">
      <div class="accordion-inner">
        <%= f.simple_fields_for :routes do |builder| %>
          <%= render 'route_fields', f: builder %>
        <% end %>
        <%= link_to_add_fields "Add Step", f, :routes %>
      </div>
    </div>
  </div>

  <div class="accordion-group">
    <div class="accordion-heading">
      <a class="accordion-toggle" data-toggle="collapse" data-parent="#accordion2" href="#collapseFive">
        Directions
      </a>
    </div>
    <div id="collapseFive" class="accordion-body collapse">
      <div class="accordion-inner">
        <%= f.simple_fields_for :directions do |builder| %>
          <%= render 'direction_fields', f: builder %>
        <% end %>
        <%= link_to_add_fields "Add More Directions", f, :directions %>
      </div>
    </div>
  </div>

</div>

Bootstrap 使用 in 类来确定默认打开哪些项目（不仅仅是在手风琴功能上），因此您可以将该类移动到 #collapseTwo div 中，它将默认打开。
