```javascript
import NestedListView, {NestedRow} from 'react-native-nested-listview'
const data = [{title: 'Node 1', items: [{title: 'Node 1.1'}, {title: 'Node 1.2'}]}]
'items'}
onNodePressed={(node) => alert('Selected node')}
renderNode={(node, level, isLastLevel) => (
{node.title}
)}

## Props
### NestedListView

## Examples
You can find examples [here](https://github.com/fjmorant/react-native-nested-listview-examples) and also an Expo project [here](https://github.com/fjmorant/react-native-nested-listview-examples-expo)
| Version App | React Native | Library |
| ----------- | ------------ | ------- |
| 1.0.0 | 0.70.1 | 0.14.0 |
## Roadmap
I have moved the roadmap of this library to this trello board so that it can be easier to add more things and like that it doesn't create issues in GitHub if I need to create a ticket
[Roadmap Trello Board](https://trello.com/b/IOMR8gFw)
## Development
In other to start watch mode and develop the library with the examples project (described above), you need to have installed the following npm packages:
- `npm -g json`
- `npm -g wml`
And have the library and examples project in the same root folder, example:
- root
- react-native-nested-listview
- react-native-nested-listview-examples
After the previous steps you can then run the following command:
`yarn start-watch`
and then you can start the examples app as usual:
`yarn ios` or `yarn android`
When you finish with watch mode remember to stop it to get back to normal like this:
`yarn stop-watch`
