I found this greate plugin:
<https://johnny.github.io/jquery-sortable/>

I would like to have possibilty to drop daggable elements into every child. I've tried to do this adding an empty `<ol></ol>` but it dosnt work on run. I would have to do this before I build sortable tree. But I do everything dynamically.

And according to documentation:

> 
> name: drop  
> 
>  default: true  
> 
>  description: If true, items can be droped onto this container
> 
> 
> 

So I understand that it should work that way out of the box?

Please help.
