Feature highlight on click for polygons without any unique properties.

[divya1c]

mapbox-gl-js version: v0.14.1

Hi!

I am trying to implement a 'highlight feature' using mapbox gl js. I saw this example - https://www.mapbox.com/mapbox-gl-js/example/hover-styles/. But, the problem is that my polygons do not have any properties that are unique to the polygon (unlike the name property in the example). Is there a way to filter based on geometry? Or any other way to highlight or change the paint property of the feature on click?

Thanks!

Nope; you'll need to add some identifying property to the data.

@jfirebaugh what would you recommend if it's not possible to add an identifying property (because i'm displaying third party data)?

@jolesbi the feature you're requesting is #200. It's something we'd love to build but haven't yet had the time.

Have you checked if your features have a unique id field? mapbox/mapbox-gl-style-spec#391
