<tr><td>enabled</td><tdclass="mid">Boolean</td><tdclass="mid"><code>false</code></td><td>Toggle the manipulation system on or off. This property is optional. If you define any of the options below and enabled is undefined, this will be set to true.</td></tr>

Take a look at the <ahref="#locales"data-scroll=""data-options="{ "easing": "easeInCubic" }">locales section below</a> for more explaination on how to customize this.</td></tr>

<preclass="code">
var options = {

addNode: function(nodeData,callback) {
nodeData.label = 'hello world';

<h3>Methods</h3>
<p>This is a list of all the methods in the public API. Options can be set directly to the module or you can use the setOptions method of the network itself and use the module name as an object name.</p>
<tr><td>enableEditMode()</td><tdclass="mid">none</td><td>Programatically enable the edit mode. Similar effect to pressing the edit button.</td></tr>

<tr><td>addNodeMode()</td><tdclass="mid">none</td><td>Go into addNode mode. Having edit mode or manipulation enabled is not required. To get out of this mode, call <code>disableEditMode()</code>. The callback functions defined in <code>handlerFunctions</code> still apply. To use these methods without having the manipulation GUI, make sure you set <code>enabled</code> to false. </td></tr>
<tr><td>editNodeMode()</td><tdclass="mid">none</td><td>Go into editNode mode. The explaination from <code>addNodeMode</code> applies here as well.</td></tr>

<h3>Events</h3>
<p>There are no events emitted by the layout module.</p>
<h3id="locales">Locales</h3>
<p>The locales object has the following format:</p>
<preclass="code">
var locales = {
en: {
edit: 'Edit',
del: 'Delete selected',
back: 'Back',
addNode: 'Add Node',
addEdge: 'Add Edge',
editNode: 'Edit Node',
editEdge: 'Edit Edge',
addDescription: 'Click in an empty space to place a new node.',
edgeDescription: 'Click on a node and drag the edge to another node to connect them.',
editEdgeDescription: 'Click on the control points and drag them to a node to connect to it.',
createEdgeError: 'Cannot link edges to a cluster.',
deleteClusterError: 'Clusters cannot be deleted.',
editClusterError: 'Clusters cannot be edited.'
}
}</pre>
<p>If you want to define your own locale, you can change the key ('en' here) and change all the string. You can then use your new key in the locale option.</p>
