WAB 2.6 Edit Widget Snap

How do you enable the snap function in order to snap to a editable feature?

Snap works fine when snapping to a graphic element but I need it to snap to a point feature and to an edge line feature.

Rich,

Are the feature you are trying to snap to added to the map as feature layers? If they are just a layer in a map service then they are really just an image in the map and thus they can not be snapped to.

Yes,

They are feature servers and can be edited both in the attribute table and by geometry.

Even if I place a new point and save it I can not then snap to it.

Rich,

I did some testing and I can see that some feature services will snap and others will not. Sounds like a call to tech support.

For me, I can snap a new line to an existing line or point feature, or a new point feature to an existing line feature. But what I really need is to snap an "existing" line to and "existing" point feature. I can't coax Collector for ArcGIS to make those snaps in the field, and consequently, can't have someone edit all those "disconnects" with a web mapping application in the office.

The SnappingManager in the JS API states that is supports specifying the target snapping layers. SnappingManager | API Reference | ArcGIS API for JavaScript 3.41 | ArcGIS Developer

But it appears the widget does not include this option. Edit widget—ArcGIS Web AppBuilder | Documentation

The Edit Widget only lets you adjust the SnappingTolerance in pixels. Based on my test this appears to snap to a grid of pixels the size of your tolerance setting.

It appears a custom Edit widget is required.
