This is kind of difficult to explain, but I'm trying to make the Sly scrolling to act like a slider. What do I mean by that? I mean that when I drag the handle, it should increase the width of mousearea, without moving it out of the place, without moving the whole of it, without moving it from it's starting place.
Here's exactly illustrated what I mean:
or like this: https://jqueryui.com/slider/#colorpicker
Is there any possibility?
