how does Wechat click to open the panel in the upper right corner of the web page 
 as shown below, 
 
 
 
 is there a way to do this? 
 I tried using Wechat js-sdk "s 
 wx.showMenuItems ({
 menuList: [] / / menu items to be displayed, all menu items are in Appendix 3 
}); 
 but it doesn"t seem to work. Is there a boss who can provide ideas?
