我正在尝试创建一个包含多个控件的可折叠面板 - 文本框、标签、下拉菜单等，但每当我使用以下代码时，都会显示折叠动画，但元素仍然可见。
这是我正在尝试做的示例:
<!DOCTYPE html>
<html>
<head>
<meta name="viewport" content="width=device-width, initial-scale=1">
<link rel="stylesheet" href="https://maxcdn.bootstrapcdn.com/bootstrap/3.3.7/css/bootstrap.min.css">
<script src="https://ajax.googleapis.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>
<script src="https://maxcdn.bootstrapcdn.com/bootstrap/3.3.7/js/bootstrap.min.js"></script>
</head>
<body>
<div class="container">
<h2>Collapsible List Group</h2>
<p>Click on the collapsible panel to open and close it.</p>
<div class="panel-group">
<div class="panel panel-default" data-toggle="collapse" data-target="#collapse1">
<div class="panel-heading">
<h4 class="panel-title">
Collapsible list group
</h4>
</div>
<div class="panel-collapse collapse show" id="collapse1">
<div class="container-fluid">
<div class="row">
<div class="col">
<span>
<label for="#txtbox">Text Here</label>
<input id="txtbox" type="text"/>
</span>
</div>
<div class="col">
</div>
</div>
</div>
</div>
</div>
</div>
</div>
</body>
</html>
一些截图来展示我在说什么:
未折叠:
折叠:
最佳答案
尝试从您希望折叠的字段中删除“show”类:
编辑:在默认情况下想要显示未折叠时包括“in”类。
<div class="container">
<h2>Collapsible List Group</h2>
<p>Click on the collapsible panel to open and close it.</p>
<div class="panel-group">
<div class="panel panel-default" data-toggle="collapse" data-target="#collapse1">
<div class="panel-heading">
<h4 class="panel-title">
Collapsible list group
</h4>
</div>
<div class="collapse in" id="collapse1">
<div class="container-fluid">
<div class="row">
<div class="col">
<span>
<label for="#txtbox">Text Here</label>
<input id="txtbox" type="text"/>
</span>
</div>
</div>
</div>
