# setContainer()

***

```javascript
/**
 * @param {String|Object} container CSS3 selector string or HTMLElement
 * @return {Void}
 */
setContainer(container)
```

***

Sets the selection container. Selection is unavailable outside this container.

Pass either a CSS3 selector string or a instance of `HTMLElement` as the first and only argument. Omitting the argument will default the container to the one defined by the [`container`](../options/container) option.
