To programmatical trigger the ScrollingMenu, create a ref and access to it like this:
```JavaScript
let items = ['Menu Item 1','Menu Item 2','Menu Item 3','Menu Item 4','Menu Item 5'];

onClick(itemIndex) {
console.log("Selected: " + items[itemIndex]);
}

render() {
return (
<ScrollingMenu
items={items}
ref={(c) => this.scrollingMenu = c}
callback={this.onClick.bind(this)}
backgroundColor="#ffffff"
textColor="#cccccc"
selectedTextColor="#000000"
itemSpacing={20} />
);
}
// Scrolling to Item 5:
this.scrollingMenu.scrollTo(5);

// Select item 5
this.scrollingMenu.select(5);

// accessing state of ScrollingMenu
this.scrollingMenu.state.selected;

```
