"reference" multi select in individual module

Hi everybody,

there is this nice type: reference property type

I am working on an individual backend element and would like to integrate a similar element. The users should be able to select multiple items and sort them.

Does anybody know, if there is any existing tool to easily implement such a functionality?

Did you try references already

The selectboxeditor allows datasources Custom Data Sources - Extending Neos with PHP & Flow - Advanced - Guide - Neos Docs

Or what do you want to implement exactly?

Thanks for your replies.

I would like to use such an element in my individual Fluid-based backend module. Is there a way to use the existing references in Fluid?
