heres a function I'm using to get the navbar dropdowns to slide down on hover instead of just popping in
这是我用来让导航栏下拉菜单在悬停时向下滑动而不是直接弹出的功能
$('.navbar .dropdown').hover(function() {
$(this).find('.dropdown-menu').first().stop(true, true).delay(250).slideDown();
}, function() {
$(this).find('.dropdown-menu').first().stop(true, true).delay(100).slideUp()
});

You can simply do this by using only css. In case of button dropdown.
您可以仅使用 css 来简单地做到这一点。在按钮下拉的情况下。
<div class="btn-group btn-hover-group">
<a href="#" id="selected" class="btn btn-default editor-submit">Action 1</a>
<a href="#" class="btn btn-default dropdown-toggle"></a>
<ul class="dropdown-menu pull-right">
<li><a href="#" id="all" class="editor-submit">Action 2</a></li>
<li><a href="#" id="matching" class="editor-submit">Action 3</a></li>
</ul>
</div>
Removed data-toggle="dropdown"from <a href="#" class="btn btn-default dropdown-toggle"></a>
删除data-toggle="dropdown"从<a href="#" class="btn btn-default dropdown-toggle"></a>
.btn-hover-group > a:hover ~ ul{
display:block;
}
.btn-hover-group > .dropdown-menu:hover{
display:block;
}
I hope this will suffice your purpose.
我希望这将满足您的目的。
