Suggestion: text box with pop-up Slider?

Hi all, I’ve been looking through the Slider style options. What I’d like to do is have something similar to the Inc/Dec style, where it’s a text box (editable Label) with buttons. But, there’s only one button, and when the user clicks on it, a vertical Slider appears, which extends outside the bounds of the text box.

I’ve seen this in a few other apps.

This doesn’t exist, right? Seems like it might be cool. Just wanted to suggest it as a Slider style option.

Or can anyone explain how to do this nicely using what’s available? I’m not really sure how to create a temporary component that extends outside the parent component’s area.
