我一直在UI最近，我真的很喜欢用Flexbox的布局的CSS控制。我需要一个能让我有可排序和可拖动的框。
我开始尝试jQueryUI的的排序，但它似乎不那么Flexbox工作得很好。它的排序，但我认为它在关于在新的位置得到了一些计算错误时它可放开？如果不是这样，我做错了什么。无论哪种方式，我会提供我的代码和的jsfiddle，所以你可以看到自己的古怪。我在寻找的行为是很好的清洁可放开占位符和用于对准要像jQueryUI的的例子是如何。为了测试点击和传说拖累。也可以尝试拖动最左边的项目到最右边。
我怎样才能解决这个问题，这样它将与Flexbox的工作吗？

JavaScript的
$(document).ready(function(){

placeholder: "ui-state-highlight"
});
$( "#sortable" ).disableSelection();
});
使用某些可排序的事件处理程序到位要移动的元素，创造出“鬼”元素。这将有助于保持弹性计算。
例如：https://jsfiddle.net/CRHain88/vv636vj4/
$(document).ready(function() {
//@JA - Logout Fuction
// Create a reusable spacer element. I added a background
// style to give indication that there was once something
// there. If you're going to style it with more complex
// design, consider making it have it's own class.
var placeholderElement = jQuery('<div style="background-color: #eee;"></div>');
$("#sortable").sortable({
placeholder: "ui-state-highlight",
// Add it before the element you're dragging.
// This assumes that you can only ever drag one element at a time.
activate: function(event, ui) {
placeholderElement.insertBefore(ui.item[0]);
// Explicitly set the height and width to preserve
// flex calculations
placeholderElement.width(ui.item[0].offsetWidth);
placeholderElement.height(ui.item[0].offsetHeight);
},
// Remove it when you're done dragging.
deactivate: function() {
placeholderElement.remove();
}
});
$("#sortable").disableSelection();
});
jQuery的排序是否有处理类似这样的水平列表，而是要激活的行为，它看起来的项目是要么float: left|right;，display: inline;或display: table-cell;的能力。这里就是检查发生在jQuery UI的1.12.1
_isFloating: function( item ) {
return ( /left|right/ ).test( item.css( "float" ) ) ||
( /inline|table-cell/ ).test( item.css( "display" ) );
},
我申请float: left;你的代码，我觉得它的表现好一点，现在：https://jsfiddle.net/1s24xpzu/
这不是一个漂亮的解决方案，我们基本上只是欺骗jQuery的，而且有可能出现意想不到的后果轻飘。但我认为它会为我的使用情况至少工作。
对于那些在这偶然和我一样：
我用例是，我想排序Flexbox的行内订购的项目清单。我尝试了上述解决方案，他们什么也没做。我也尝试添加一个浮动的第一个元素（因为这是它检测到），但没有帮助所有的东西。
我所做的，而不是为改变isFloat功能（请注意，这应该叫isHorizontalSort）是这样的：
_isFloating: function( item ) {
return ( /left|right/ ).test( item.css( "float" )) ||
( /inline|table-cell/ ).test( item.css( "display" )) ||
(
( /flex/ ).test( item.parent().css( "display" )) && ( /row|row-reverse/ ).test( item.parent().css( "flex-direction" ) )
)
},
所以它检测如果孩子是水平Flexbox的内侧（弯曲方向是行或行反向）。我还设置了tolerance选项，pointer，这似乎给了最好的结果。
