Create a draggable on the mousedown event

Create a draggable on the mousedown event


While I have hundreds of draggables, the performance is very
dramatical.
So I want to hear from you if its possible to write code around it.
Have you devs a solution to create a draggable on the mousedown
event?
The problem I face now, is: that I can create on the mousedown a
draggable, but it wont following my mouse. If I reclick it, then it
follows my mouse.
How to deal with this, is there a suggestion, or fix for this?
