Sliding div's -建议

Question

我刚刚编写了这段代码来隐藏div，直到标题被点击，效果很好，只是现在我有三个div在彼此下面，我只想要第一个被展开，然后当另一个被单击时，打开的被关闭，新的被展开。我的Jquery在下面

$(function(){
    $('.drop-dwn').click(function(){
        $(this).next('.slide1').slideToggle(300);
        return false;
    });
});

我的HTML标记是：

<div class="slide-panels">
                    <h4 class="drop-dwn">Oil & Gas</h4>
                        <div class="slide1">
                            <div class="checkbox"><input type="checkbox" name="" value=""> All</div>
                            <div class="checkbox"><input type="checkbox" name="" value=""> All</div>
                            <div class="checkbox"><input type="checkbox" name="" value=""> All</div>
                        </div>
                    <h4>SAP & Enterprise Solutions</h4>
                        <div class="slide2">
                            <div class="checkbox"><input type="checkbox" name="" value=""> All</div>
                            <div class="checkbox"><input type="checkbox" name="" value=""> All</div>
                            <div class="checkbox"><input type="checkbox" name="" value=""> All</div>
                        </div>
                    <h4>IT & Change Management</h4>
                        <div class="slide3">
                            <div class="checkbox"><input type="checkbox" name="" value=""> All</div>
                            <div class="checkbox"><input type="checkbox" name="" value=""> All</div>
                            <div class="checkbox"><input type="checkbox" name="" value=""> All</div>
                        </div>
                     </div>

<div class="slide-panels">
    <h4 class="drop-dwn">Oil & Gas</h4>
        <div class="first slide1">
            <div class="checkbox"><input type="checkbox" name="" value=""> All</div>
            <div class="checkbox"><input type="checkbox" name="" value=""> All</div>
            <div class="checkbox"><input type="checkbox" name="" value=""> All</div>
        </div>
    <h4 class="drop-dwn">SAP & Enterprise Solutions</h4>
        <div class="slide1">
            <div class="checkbox"><input type="checkbox" name="" value=""> All</div>
            <div class="checkbox"><input type="checkbox" name="" value=""> All</div>
            <div class="checkbox"><input type="checkbox" name="" value=""> All</div>
        </div>
    <h4 class="drop-dwn">IT & Change Management</h4>
        <div class="slide1">
            <div class="checkbox"><input type="checkbox" name="" value=""> All</div>
            <div class="checkbox"><input type="checkbox" name="" value=""> All</div>
            <div class="checkbox"><input type="checkbox" name="" value=""> All</div>
        </div>
</div>​

jQuery：

$('.first').slideDown(300);
$(function(){
 $('.drop-dwn').click(function(){
    $('.slide1').slideUp(300);
    $(this).next('.slide1').slideToggle(300);
    return false;
 });
});​

CSS：

.slide1{
  display:none;
 }​

诀窍是slideUp所有的div，然后slideDown你点击的那个。

所以给所有的div一个公共的类，比如'panel‘和

$('.drop-dwn').click(function(){
   var _this = this;
   $(".panel").slideUp("fast", function() {
      $(_this).slideDown("fast");
   });
});
