通过单击另一个展开/折叠 div

Question

我希望创建一个在单击完全独立的非父 div 元素时展开和折叠的 div。

下面是我喜欢并一直在搞乱的扩展/折叠效果的示例。我不确定如何最好地修改下面的代码，以便我可以点击位于侧边栏中的 div，并导致位于标题下方的另一个 div 展开/折叠，将其下方的所有内容向下推。

相关的展开/折叠 div 的内容可能是一个搜索栏，例如，用户可以通过单击侧边栏按钮来显示/隐藏它。

$(".header").click(function () {

    $header = $(this);
    //getting the next element
    $content = $header.next();
    //open up the content needed - toggle the slide- if visible, slide up, if not slidedown.
    $content.slideToggle(500, function () {
        //execute this after slideToggle is done
        //change text of header based on visibility of content div
        $header.text(function () {
            //change text based on condition
            return $content.is(":visible") ? "Collapse" : "Expand";
        });
    });

});

.container {
    width:100%;
    border:1px solid #d3d3d3;
}
.container div {
    width:100%;
}
.container .header {
    background-color:#d3d3d3;
    padding: 2px;
    cursor: pointer;
    font-weight: bold;
}
.container .content {
    display: none;
    padding : 5px;
}

$(".header").click(function() {
  $('.content').slideToggle().toggleClass('active');
  if ($('.content').hasClass('active')) {
    $('.header span').text('Collapse');
  } else {
    $('.header span').text('Expand');

$('button').click(function(){

    //getting the content 
    $content = $(".content")
    //open up the content - toggle the slide- if visible, slide up, if not slidedown.
    $content.slideToggle(500, function () {
        //execute this after slideToggle is done
        //change text of header based on visibility of content div
        $header.text(function () {
