点击More按钮时禁止Accordion展开或折叠的技术需求

点击More按钮时，Accordion不得展开或折叠。若Accordion初始状态为展开，点击按钮后需保持展开；若初始为折叠，则点击后仍保持折叠。即点击More按钮对Accordion无任何影响。

问题核心是More按钮嵌套在Accordion的触发按钮内部，点击时事件会向上冒泡，触发父级Accordion的折叠/展开逻辑。只需阻止点击More按钮及其下拉菜单项时的事件冒泡，即可让Accordion保持原状态。

修改步骤 #

在现有JavaScript代码中添加以下事件监听：

// 阻止More按钮的点击事件冒泡到Accordion按钮
$("#abc").on('click', '.dropdown-toggle', function(event) {
  event.stopPropagation();
});

// 阻止下拉菜单项的点击事件冒泡
$("#abc").on('click', '.dropdown-item', function(event) {
  event.stopPropagation();
});

原理说明 #

• event.stopPropagation()会阻止事件向上传递到父元素，点击More按钮时，父级的Accordion触发按钮不会收到点击事件，也就不会执行折叠/展开逻辑。
• 同时处理下拉菜单项的点击事件，避免点击菜单项时也触发Accordion的状态变化。
