Hi saad

As I understand you want to update some “order” field in table after d&d/sortable in UI, right?
if so, I can propose you to take a look at this https://laracasts.com/discuss/channels/laravel/best-way-of-updating-a-dragdrop-sorting-list-on-the-db-side?page=1 or here
https://themeteorchef.com/tutorials/adding-drag-and-drop-sorting-to-lists

It’s not related to Backendless but you can see a conception of how to change ordering on the server

So you need to:

  1. have a some “order” column in table (for sorting items)
  2. in UI, after d&d/sorting update “order” property for all items

Also you can create API Service in BusinessLogic for that

Hello @Vinod_Sahu

At this moment there is no such functionality to d&d elements in the UI-Builder. However I assume it might be accomplished by adding some kind of arrow icons in each ListItem.

What’s the situation at this moment? Im in need of d&d reordering func :confused:

Hello @Nico_Kivinen

We haven’t added the ability yet.
At this moment, we are working on Custom Components which will enable creating components with any custom JS code and such issues will be solved much faster.
