我知道问题是关于菜单滚动但是根据您的要求，您可以使用panel作为叠加层，并且可以使用grid在面板内使用checkboxmodel。

您需要在设置按钮点击时使用showBy()方法。

带有覆盖面板的屏幕截图，可单击多个按钮。

在此 FIDDLE 中，我使用panel和grid创建了一个演示。希望这有助于/指导您实现您的要求。

Ext.application({
    name: 'Fiddle',

    launch: function () {
        //Common button click on setting button
        function onButtonClick(btn, e) {
            //If menu is alredy created for that button no need to create directly show or hide
            var myMenu = btn.myMenu;

            //If menu is not create then need to create
            if (!myMenu) {
                myMenu = btn.myMenu = Ext.create({
                    xtype: 'custommenu',
                    title: btn.getText()
                });
            }
            myMenu.isHidden() ? myMenu.showBy(btn, "bl") : myMenu.hide();
        }

        //Define common store for grid menu
        Ext.define('MenuStore', {
