如果你想要更多的東西闡述,你可以放在一起真棒Animate.css,(跨CSS動畫瀏覽器庫),一些jquery,當然還有Twitter Boostrap。
在您的標題:
<head>
...
<link rel="stylesheet" href="https://cdnjs.cloudflare.com/ajax/libs/animate.css/3.5.2/animate.min.css">
<link rel="stylesheet" href="https://maxcdn.bootstrapcdn.com/bootstrap/3.3.7/css/bootstrap.min.css" integrity="sha384-BVYiiSIFeK1dGmJRAkycuHAHRg32OmUcww7on3RYdg4Va+PmSTsz/K68vbdEjh4u" crossorigin="anonymous" />
</head>
在你的身體要在其中創建下拉:
<div class="dropdown" data-animation="slideInDown,slideOutUp,600">
<button type="button" class="btn btn-primary" data-toggle="dropdown">Click to toggle animated dropdown <i class="caret"></i></button>
<ul class="dropdown-menu">
<li><a href="#">Action</a></li>
<li><a href="#">Another action</a></li>
<li><a href="#">Something else here</a></li>
<li class="divider"></li>
<li><a href="#">Separated link</a></li>
</ul>
</div>
注意在標記數據的動畫屬性,您必須提供3個參數,動畫中,動畫和持續時間。
如果你喜歡other animations,你可以玩。

希望這有助於!
需要完整的示例?
$(function() {
var $in, $out, $duration;
$('.dropdown')
.on('shown.bs.dropdown',
function (e) {
if ($(this).attr('data-animation')) {
let $animations = [];
const $animation = $(this).data('animation');
$animations = $animation.split(',');
$in = 'animated ' + $animations[0];
$out = 'animated ' + $animations[1];
$duration = '';
if (!$animations[2]) {
$duration = 500;
} else {
$duration = $animations[2];
}
$(this).find('.dropdown-menu').removeClass($out);
$(this).find('.dropdown-menu').addClass($in);
}
});
$('.dropdown')
.on('hide.bs.dropdown',
function (e) {
if ($(this).attr('data-animation')) {
e.preventDefault();
const $this = $(this);
const $targetControl = $this.find('.dropdown-menu');
$targetControl.addClass($out);
setTimeout(function() {
$this.removeClass('open');
},
$duration);
}
});
