+# cytoscape.js-edge-editation
+Extension for Cytoscape.js, which adds handles to nodes and allows to create different types of edges
+
+
+## Dependencies
+
+Extension was tested with these versions of libraries:
+
+* jQuery 2.1.1
+* Cytoscape.js 2.6.0
+
+## Install
+
+Use git clone or direct zip download and unpack archive into your project. Then, simply insert \<script\> tag after
+Cytoscape.js and jQuery:
+
+```html
+<script src="https://code.jquery.com/jquery-2.2.0.min.js"></script>
+<script src="cytoscape.js"></script>
+<script src="CytoscapeEdgeEditation.js"></script>
+```
+
+## How to use
+
+First, you need to initialize extension. After initializing Cytoscape.js:
+
+```js
+var cy = cytoscape({...});
+var handles = new CytoscapeEdgeEditation;
+handles.init(cy);
+```
+
+Then, you need to register handles to certain node types:
+
+```js
+handles.registerHandle({
+    positionX: "left",          //horizontal position of the handle  (left | center | right)
+    positionY: "center",        //vertical position of the handle  (top | center | bottom)
+    color: "#48FF00",           //color of the handle 
+    type: "some_type",          //stored as data() attribute, can be used for styling            
+    single: true,               //wheter only one edge of this type can start from same node (default false) 
+    nodeTypeNames: ["type2"]    //which types of nodes will contain this handle
+    noMultigraph: false         //whereter two nodes can't be connected with multiple edges (does not consider orientation) 
+});
+
+handles.registerHandle({...});
+handles.registerHandle({...});
+```
+
+Type of node is stored in data section:
+
+```js
+cy.add({
+    data: { id: 'n4', type: "type2"},
+});
+```
