I already asked this question here. Is it possible to have group color input slider in Color Ramp Node?
That's exactly what referring to, and yes I tried that and it doesn't help here. You can add driver for pos but not for slider. There's no such option in right click context menu.
You can't close the thread simply without any testing. Referring to other similar topic? Did you even tested yourself what I'm trying to achieve? if so then your link provide no help to me.
