ruby-on-rails - 在 Rails 中创建多个链接的下拉列表

Question

我有很多链接，例如 link1、link2、link3、link4 ...link9。我必须在下拉列表中添加这些链接。我尝试使用 Rails select_tag 和 html 标签

使用 html 选择标签

<span class="device_update">
    <select>
      <option value="link1"><%= link_to "link1", "#",{:remote => true, 'data-toggle' =>  "modal", 'data-target' => '#modal-window'} %></option>
      <option value="link2"><%= link_to "link2", "#",{:remote => true, 'data-toggle' =>  "modal", 'data-target' => '#modal-window'} %></option>
      <option value="link3"><%= link_to "link3", "#",{:remote => true, 'data-toggle' =>  "modal", 'data-target' => '#modal-window'} %></option>
           ......

      <option value="link9"><%= link_to "link9", "#",{:remote => true, 'data-toggle' =>  "modal", 'data-target' => '#modal-window'} %></option>
        </select>
    </span>

如何制作多个链接的下拉列表

Answer 1

我通过以下方式做到了这一点。为此我引用bootstrap button dropdowns

<div class="btn-group">
      <button type="button" class="btn btn-default dropdown-toggle" data-toggle="dropdown">
        Action <span class="caret"></span>
      </button>
      <ul class="dropdown-menu" role="menu">
        <li><%= link_to "link1", "#",{:remote => true, 'data-toggle' =>  "modal", 'data-target' => '#modal-window'} %></li>
        <li><%= link_to "link1", "#",{:remote => true, 'data-toggle' =>  "modal", 'data-target' => '#modal-window'} %></li>
        <li><%= link_to "link3", "#",{:remote => true, 'data-toggle' =>  "modal", 'data-target' => '#modal-window'} %></li>
        <li class="divider"></li>
        <li><%= link_to "link4", "#",{:remote => true, 'data-toggle' =>  "modal", 'data-target' => '#modal-window'} %></li>
      </ul>
    </div>
