Child element of the `<Layout>` component.

By default uses the main type, to span the full width of the Layout area. Split left and split right provide a fixed left/right area. Layout only supports one type of each.

### Usage

```js
import { LayoutItem } from 'nr1'
```

### Props

| `children` REQUIRED node | Content to display inside the child item.                                                                                                                                                                                                                                                                                                                           |

| `className` string       | Appends class names to the component.                                                                                                                                                                                                                                                                                                                               |
| `sizeType` enum          | Determines the width of the layout item. We recommend you use the small size for navigation purposes (ex. sidebars) and the medium size for showing contextualized information (ex. activity stream).Size type only works on SPLIT_LEFT and SPLIT_RIGHT items. LayoutItem.SIZE_TYPE.MEDIUM, LayoutItem.SIZE_TYPE.SMALL,                                             |
| `style` object           | Inline style for custom styling.                                                                                                                                                                                                                                                                                                                                    |
| `testId` string          | Adds a `data-test-id` attribute. Use it to target the component in unit and E2E tests.For a test id to be valid, prefix it with your nerdpack id, followed up by a dot.For example, `my-nerdpack.some-element`. **Note:** You might not see `data-test-id` attributes as they are removed from the DOM, to debug them pass a `e2e-test` query parameter to the URL. |
| `type` enum              | Type can be: - Main — Used to place the main content on each view. It spans the full width of the layout area. - Split left — Render as a fixed area on the left of the layout. - Split right — Render as a fixed area on the right of the layout. LayoutItem.TYPE.MAIN, LayoutItem.TYPE.SPLIT_LEFT, LayoutItem.TYPE.SPLIT_RIGHT,                                   |
