Is there any way to manage the internal state of sortable programmatically?

[SyedMSawaid]

My rough requirements are that I want to change or order the sortable programmatically from javascript. I expect some sort of API to manage that. For instance, the Angular2-tree library has API methods to deal with it (https://angular2-tree.readme.io/docs/calling-methods-on-the-tree)

I saw a similar discussion here at #1998, but I can't find my answer.

You can easily obtain the internal state:
let elems = sortable.toArray();
Then you can alter the array and update sortable with the altered array:
sortable.sort(elems, true);

When creating the Sortable instance you can tell Sortable what attribute you want to use - so you can assign a unique ID to each element:

dataIdAttr: 'data-yourid'

And add that data-yourid = "xxx" to each HTML element.
Works very well - and it's all in the docuentation.
