+- Type: `boolean` | [`Connector`](/typedocs/types/Connector.html/)
+
+- Default: `false`
+
+- Details:
+
+  When connection is emitted, automatically create a new edge from params.
+
+  Also accepts a [`Connector`](/typedocs/types/Connector.html/) which returns an edge-like object or false (if creating an edge is not allowed).
+
+  This option can be used as a shorthand for `onConnect((params) => addEdges([params]))`.
+
+#### Examples
+
+##### Boolean value
