新增一个div

<div class="my-panel gjs-pn-panel ">


</div>

css

.my-panel{
    position: absolute;
    z-index:4;
    right: 0;
    top: 40px;
 height: calc(100% - 40px);
 width: 15%;
}

const myPanel = editor.Panels.addPanel({
  id: 'my-panel',
  el: '.my-panel',
  visible: true,
});

pannel显示与隐藏代码

const myPanel = editor.Panels.getPanel('my-panel');
myPanel && myPanel.set('visible', false);//改成true为显示
