# Using a React library

This example shows how to import and use Material UI.

Add the [library CDN](https://v4.mui.com/components/buttons/) to the widget's *3rd party libraries*:

```
https://unpkg.com/@material-ui/core@4.11.4/umd/material-ui.development.js
```

In this path, `umd` indicates that the CDN bundle uses the UMD format.

In the code editor's HTML tab, add the following:

```html
<div id="root"></div>
```

Switch to the JavaScript (JSX) tab and paste the following:

```javascript
const { createRoot } = ReactDOM;
const { Button } = MaterialUI;


function App() {
    return (
        <>
            <Button variant="contained" color="primary">
                First button using React and Material UI
            </Button>
            <Button variant="outlined" color="secondary">
                Another button
            </Button>
        </>
    );
}


```

After you save the changes, the widget renders like this:

# Agent Instructions
This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation by asking a question.

Perform an HTTP GET request on the following URL with the `ask` and `goal` query parameters:

```
GET https://dev.ubidots.com/dashboards-and-widgets/html-canvas/examples/using-a-react-library.md?ask=<question>&goal=<user_goal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is what the user is ultimately trying to achieve, the reason they need the answer. Sharing it helps GitBook give you a better, more relevant answer. A goal is most helpful when it describes the outcome the user wants rather than restating the question. For example, with `ask=how do I create an API token`, a goal like `automate deployments from our CI pipeline` lets GitBook tailor the answer to that use case.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
