| 15 | + <h1>How to integrate GridStack.js with Vue.js</h1> |
| 16 | + <p> |
| 17 | + As with any virtualDOM-based framework, you need to check if Vue has |
| 18 | + rendered the DOM (or any updates to it) <strong>before</strong> you |
| 19 | + initialize GridStack or call its methods. As a basic example, check this |
| 20 | + component's <code>mounted</code> hook. |
| 21 | + </p> |
| 22 | + <p> |
| 23 | + If your app requires more complex render logic than the inline template |
| 24 | + in `addWidget`, consider |
| 25 | + <a |
| 26 | + href="https://github.com/gridstack/gridstack.js/tree/develop/doc#makewidgetel" |
| 27 | + >makeWidget</a |
| 28 | + > |
| 29 | + to let Vue deal with DOM rendering. |
