我在主干中有一个问题，我想从后端渲染 100 行数据（通过 url 获取）并在按钮元素和分页之间显示。我创建了两个模板，并且有两个视图，一个用于整个页面，另一个用于单个项目。但是当我获取数据时，它们不会在按钮和分页 div 之间移动，所有 100 行都在它之下。我怎样才能把它们放在合适的地方？这些是我的模板：
列表模板：
<div class="message-list-actions">
<div class="action">
<select>
<option value="0">Bulk Actions</option>
<option value="1">Delete</option>
<option value="2">Mark As Read</option>
</select>
<button class="grey">OK</button>
</div>
<div class="action">
<select>
<option value="0">All</option>
<option value="1">Unread Messages</option>
<option value="2">Read Messages</option>
</select>
<button class="grey">OK</button>
</div>
<div class="results right">
<form>
<label for="results">Results pr. page</label>
<select name="results">
<option value="25">25</option>
<option value="50">50</option>
<option value="100">100</option>
<option value="500">500</option>
</select>
</form>
</div>
</div> <!-- message-list-actions -->
<div class="message-list">
<div class="message-list-header row">
<div class="left check">
<input type="checkbox" name="type"/>
<label for="type">CHECK ALL</label>
</div>
<div class="left date" >
<span class="sorter">Date</span>
</div>
<div class="large-9 columns" >
<span class="sorter">Message</span>
</div>
</div>
<section class="message-item row">
<div class="message-list"></div>
<div class="left check" >
<input type="checkbox" class="type">
</div>
<div class="left date" >
<div class="icon"></div>
</div>
<div class="large-9 columns" >
</div>
</section>
<section>
<ul class="pagination">
<li class="arrow unavailable"><a href="">Previous</a></li>
<li class="current"><a href="">1</a></li>
<li><a href="">2</a></li>
<li><a href="">3</a></li>
<li><a href="">4</a></li>
<li class="unavailable"><a href="">…</a></li>
<li><a href="">12</a></li>
<li><a href="">13</a></li>
<li class="arrow"><a href="">Next</a></li>
</ul>
</section>
其他模板：
<div class="message-list">

<div class="left date" >
<p><%= created !== undefined ? created : "not available" %></p>

<div class="large-9 columns" >
<h4><a href="#messageDetailsView"><%= title %></a></h4>
<p><%= id %></p>
</div>
<!-- <a href="#" class="delete">Delete</a> -->
</section>
</div> <!-- .main -->
