# 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"},
});
```
