You can procedurally add or remove items.

- `insert(index, item, [silent])`
- `remove(component, [destroyItem], [silent])`
- `removeAt(index, [destroyItem], [silent])`



<pre class="runnable readonly text 100">
this.add({
    module: Button,
    text: 'New Button'
});
</pre>

<pre class="runnable readonly text 160">
this.add([{
    module: Button,
    text: 'One'
}, {
    module: Button,
    text: 'Two'
}]);
</pre>
