angular.js - When doing drag-and-drop interaction in angular, is it better to use js to change the dom, or only change the data?

Online searches recommend not to change the DOM, but changing only the data will cause re-rendering, and the originally opened drop-down items will be closed. The interaction effect is not good. But if you use js to change the dom, the data will become difficult to process.
