Hi @keen raven, please do not post pictures/screenshots of code (especially photos of a physical screen). Screenshots are more difficult to read compared to code in a codeblock, and they do not allow people answering to quickly copy and adjust your code to provide you with an answer.

For copy/pasting code in a discord post, you can use the following snippet to have your code placed in a codeblock with syntax highlighting. Replace ts with the language you are copying (i.e. html, js, css, etc)

```ts
// your code goes here
```

See #how-to-get-help for more tips on how to ask code related questions in this server.

The error messages are telling you what it's expecting. What does the Material documentation tell you about the attributes required for that element?
