<h1>How to integrate GridStack.js with Vue.js</h1>
<p>
As with any virtual DOM based framework, you need to check if Vue has
rendered the DOM (or any updates to it) <strong>before</strong> you
initialize GridStack or call its methods. As a basic example, check this
component's <code>mounted</code> hook.
</p>
<p>
If your app requires more complex render logic than the inline template
in `addWidget`, consider
<a

>makeWidget</a

to let Vue deal with DOM rendering.
