Drag and Drop not working correctly

[Caio Kawasaki]

I'm creating an application but my drag and drop is not working properly, especially in the first level. What can it be?

Also store.deleteNode is not working...

I put my code here: https://codesandbox.io/s/03z75682yl

Another bug I encountered trying to solve the problem: Sometimes the steps duplicate.

Strange because a while ago everything worked correctly, I spent some time without messing with the project and now that I came back with the project the plugin does not want to work correctly

Hi. I spent hours to check it. This issue is caused by Vue@2.6 latest.
In your demo: https://codesandbox.io/s/03z75682yl
package.json, change "vue": "^2.5.22" to "vue": "2.5.22", then it works because vue 2.5 is using.

This is an issue of vue-draggable-nested-tree. It don't work with Vue 2.6, so you get it. Fixed in 2.2.6
