How to combine case expression and property in styling line-color?

[kldziwon]

Hi,
I'm stuck with styling line-color. I want to achieve something like this below, but I don't know how to get color combining colorId and stops in case expression

    'line-color': ['case',
      ['==', ['get', 'isOpen'], true], *use color based on property colorId and stops*, '#878787',
    ],

I've tried, but it didn't worked

    'line-color': ['case',
  ['==', ['get', 'isOpen'], true], {stops, property: 'colorId'}, '#878787',
],

I believe what you looking for might be line gradients. Which generally achieve these stop-based rendering of colors on lines. But unfortunately, you're trying to get the color stops inferred from the data, and we currently do not support data driven line gradients.

I'll close as duplicate of #8977, but feel free to reopen if I misunderstood your use case.
