Enable all layers for snapping

Question

Hi all,

In edit widget i want to enable all layers snapping, i used this code:

snappingOptions: { // autocasts to SnappingOptions()
    enabled: true, // global snapping is turned on
    // assigns a collection of FeatureSnappingLayerSource() and enables feature snapping on this layer
    featureSources: [{ layer: myFlLayer1, myflLayer2, enabled: true }]
  }

but, it des not work.

How can i pass several layers in featureSources?

Thanks

Thank you @Sage_Wall , i see, i did not try to add FLs as objects and map.allLayers i couldn't think about it.

Thanks again

Hi @Vakhtang_Zubiashvili ,

You need to have a collection of FeatureSnappingLayerSource . So with three layers (the second one is not enabled) it might look something like this

featureSources: [{ layer: myFlLayer0, enabled: true }, { layer: myFlLayer1, enabled: false}, { layer: myFlLayer2, enabled: true }]

If you really want to enable snapping on all layers in your map you could probably do something like this but I haven't checked to see if this actually works.  I think it should, but you might have to filter the allLayers collection first to just the layer types supported in featureSources

snappingOptions: { 
    enabled: true, 
    featureSources: map.allLayers
  }
