 We're working on implementing HTML5 drag'n'drop through the plugin system. Right now it is still jquery-ui based. Because of that we are still bundling `jquery` (3.5.1) + `jquery-ui` (1.12.1 minimal drag|drop|resize) internally in `gridstack.all.js`. IFF your app needs to bring your own version instead, you should **instead** include `gridstack-poly.min.js` (optional IE support) + `gridstack.min.js` + `gridstack.jQueryUI.min.js` after you import your JQ libs. But note that there are issue with jQuery and ES6 import (see [1306](https://github.com/gridstack/gridstack.js/issues/1306)).
 
-Note: v2.0.-rc does not currently support importing GridStack Drag&Drop without also including our jquery + jqueryui. Still trying to figure how to make that bundle possible.

 You can call it on a single event name, or space separated list like:
