侧边栏具有更高的z-index。 容器 .main 具有 overflow: none， 其内部的 div 具有 overflow:scroll code> 但由于某种原因，当您拖动文本时，它认为它位于 .scrolling div 上，而实际上它位于 侧边栏 div.

我注意到的第一件事是你的 helper 回调配置不正确，你有:
$('.drag').draggable({
helper() {
const $helper = $('<div></div>');
$helper.text('drag');
return $helper.clone().addClass('dragged-component-helper');
},
start() {
},
由于您要定义一个对象，因此您需要有键名、冒号，然后是函数。示例:
$('.drag').draggable({
helper: function() {
const $helper = $('<div></div>');
$helper.text('drag');
return $helper.clone().addClass('dragged-component-helper');
},
start: () => {
},
这可能会导致您的可拖动对象出现各种初始化问题，但令我惊讶的是它没有在您的控制台中显示为错误。
关于拖动 Action ，我认为这也会通过修正得到解决。

JavaScript
$(function() {
$('.scrolling').droppable({
tolerance: 'pointer',
accept: '.drag',
drop(event, ui) {
if (ui.helper.hasClass('cancelled')) {
return false;
}
$(this).append(ui.helper.clone().css({
left: (ui.offset.left - $(".sidebar").width()) + "px",
top: ui.offset.top + "px"
}));
},
});
$('.drag').draggable({
helper: function() {
return $("<div>", {
class: "drag component"
}).html("drag");
},
stop(event, ui) {
ui.helper[0].remove();
},
cursorAt: {

top: 5,
},
cancelOnEscape: true,
appendTo: '#content',
disabled: false,
