我遇到bootstrap ui折叠指令的问题，它显示为默认打开状态，我需要在页面加载时折叠，我正确设置变量但仍然无法正常工作Bootstrap ui Collapse默认打开
这里是我的代码部分：
aside class="col-md-3 leftSidebar separator-right" ng-controller="Collapse as vm">
<div class="row separator">
<div class="sidebarPosition">
<div class="leftSidebar__toggle">
<a class="mod" ng-click="vm.isCollapsedLeft = !vm.isCollapsedLeft"><span class="fa fa-bars"></span> Outline</a>
<ul uib-collapse="vm.isCollapsedLeft">
<li><a href="#scientific_abstract" du-smooth-scroll>Scientific Abstract</a></li>
<li><a href="#layperson_abstract" du-smooth-scroll>Layperson’s Abstract</a></li>
<li><a href="#introduction" du-smooth-scroll>Introduction</a></li>
<li><a href="#">Results</a></li>
<li><a href="#">Discussion</a></li>
<li><a href="#">Methods</a></li>
<li><a href="#">Additional Information</a></li>
<li><a href="#">Change History</a></li>
<li><a href="#">Acknowledgements</a></li>
<li><a href="#">Author Information</a></li>
<li><a href="#">Author Contributions</a></li>
</ul>
</div>
</div>
</div>
<div class="row leftSidebar__sections">
<ul>
<li><a ui-sref="article.figures"><span class="fa fa-picture-o"></span> Figures</a></li>
<li><a ui-sref="article.references"><span class="fa fa-link"></span> References</a></li>
<li><a href="#"><span class="fa fa-retweet"></span> Related</a></li>
<li>
<a href="#"> <span class="fa fa-area-chart"></span> Stats Impact</a>
</li>
<li><a ui-sref="article.comments"><span class="fa fa-comment"></span> Comments</a></li>
</ul>
</div>
</aside>
我的控制器：
(function() {
'use strict';
angular
.module('app.bootstrap')
.controller('Collapse', Collapse);
function Collapse() {
var vm = this;
vm.isCollapsedLeft = false;
vm.isCollapsedRight = false;
}
})();
