You just need to change this:
你只需要改变这个：
<div class="panel-body">
To this :
对此：
<div class="panel-body" style="display:none;">
And change the slideUp() by slideDown(), and the same for slideDown() by slideUp().
并通过slideDown()更改slideUp()，通过slideUp()更改slideDown()。
Also change this:
也改变这个：
<span class="pull-right clickable collapse in"><i class="glyphicon glyphicon-plus"></i></span>
To this:
对此：
<span class="pull-right clickable collapse in"><i class="glyphicon glyphicon-minus"></i></span>
Everything should work as you mentioned in your question now.
现在一切都应该像您在问题中提到的那样工作。

You could use the Bootstrap collapsecomponent which already has most of the logic you need:
您可以使用 Bootstrap折叠组件，它已经拥有您需要的大部分逻辑：
<div class="panel-heading">
<h3 class="panel-title">Panel 1</h3>
<button class="btn btn-primary pull-right" type="button"
data-toggle="collapse" data-target="#collapseExample">
<i class="glyphicon glyphicon-plus"></i>
</button>
</div>
<div class="collapse" id="collapseExample">
<div class="panel-body">Panel content</div>
</div>
In addition you only need a small JavaScript to change the button icon:
此外，您只需要一个小的 JavaScript 来更改按钮图标：
$(document).on('click', '.panel-heading button', function(e) {
var $this = $(this);
var icon = $this.find('i');
if (icon.hasClass('glyphicon-plus')) {
$this.find('i').removeClass('glyphicon-plus').addClass('glyphicon-minus');
} else {
$this.find('i').removeClass('glyphicon-minus').addClass('glyphicon-plus');
}
});

I am sharing a reference code for you, just follow the code, there is no need of any click function, bootstrap 'data-toggle="collapse"' handles it automatically.
给大家分享一个参考代码，跟着代码走，不需要任何点击功能，bootstrap 'data-toggle="collapse"' 自动处理。
CODE:
代码：
<div class="panel-group" id="steps">
<!-- Step 1 -->
<div class="panel panel-default">
<div class="panel-heading">
<h4 class="panel-title">
<a data-toggle="collapse" data-parent="#steps" href="#stepOne"><SPAN TAG></a>
</h4>
</div>
<div id="stepOne" class="panel-collapse collapse">
<div class="panel-body">
<div class="form-group">
<label class="col-lg-2 control-label">Sub-Category Name</label>
</div>
</div>
</div>
</div>
</div>
Just put the span tag in place of and use class pull-right, the bootstrap icon which one you need http://getbootstrap.com/components/
只需将 span 标签代替并使用类 pull-right，即您需要的引导程序图标http://getbootstrap.com/components/
I hope this will work.
我希望这会奏效。
