How can I merge features in ArcGIS Online?

[NatalieScott1]

I am building an ArcGIS Online system for a client and one of their requests is that they would like to be able to merge features using the editor widget. For example, they might have two distinct lengths of pipe that are coincident at the ends. They would like to merge these to be one single length of pipe. Is this possible is AGOL? From what I've seen, the editing toolset seems relatively limited.

May be worth mentioning that their datasets are mostly lines (not polygons).

Thanks,

Natalie

Personally, developers can do something (below) to meet the customer's requirements like 'Merge features', in which way it will rely on your data in ArcGIS Online:

1. Use 'Merge Layers', if features from two layers. Refer to Perform analysis—ArcGIS Online Help | ArcGIS

2. Manually merge the features inside one layer at Edit features—ArcGIS Online Help | ArcGIS

3. Custom the widget to automatically merge features by Web AppBuilder for ArcGIS (Developer Edition) | ArcGIS for Developers
