## Import

```jsx
import { MessageBlock } from "@cfa/react-core";
```

## Live Editor

```jsx
<MessageBlock.Root>MessageBlock content goes here.</MessageBlock.Root>
```

## Guidelines

### When to use

- MessageBlock is for a message tied to a field, form, or section, such as validation errors at the top of a form.

### Do

- Use variant for severity: info, success, warning, or error.
- Keep copy short and actionable. Say what happened and what to do next, if anything.
- Keep error messages until people dismiss them or resolve the issue.
- Include a dismiss control. Leave it off when the message must stay visible until it is resolved.

### Avoid

- Using MessageBlock for a transient acknowledgment. Use Toast.
- Using MessageBlock for a system or page-level message. Use BannerMessage.
- Stacking multiple MessageBlocks on one screen. Show the most important message.

## Examples

### Title

This example shows how to use the `MessageBlock.Title` component to apply a pre-styled Title element. This is an extension of the `Heading` component and has all the props associated with it.

```jsx
<MessageBlock.Root>
  <MessageBlock.Title>Title</MessageBlock.Title>
  MessageBlock content goes here.
</MessageBlock.Root>
```

### Severity

Use the `severity` prop to set the severity of the message block. The default is `info`. The available options are: `info`, `success`, `warning`, `error`.

```jsx
<div style={{ display: "flex", flexDirection: "column", gap: "1rem" }}>
  <MessageBlock.Root severity="info">
    <MessageBlock.Title>Info</MessageBlock.Title>
  </MessageBlock.Root>
  <MessageBlock.Root severity="success">
    <MessageBlock.Title>Success</MessageBlock.Title>
  </MessageBlock.Root>
  <MessageBlock.Root severity="warning">
    <MessageBlock.Title>Warning</MessageBlock.Title>
  </MessageBlock.Root>
  <MessageBlock.Root severity="error">
    <MessageBlock.Title>Error</MessageBlock.Title>
  </MessageBlock.Root>
</div>
```

### Dismissible

When using the `onDismiss` prop, the "close" `IconButton` will render in the top right.

```jsx
<MessageBlock.Root
  onDismiss={() => {
    alert("Closs button clicked");
  }}
>
  Lorem ipsum dolor sit amet consectetur adipisicing elit. Veritatis est placeat soluta ad impedit
  pariatur, nam perferendis provident voluptatem possimus quaerat aperiam illo consequatur odio.
</MessageBlock.Root>
```

### Customized

The `MessageBlock` component's `Icon` can be overriden using the `iconOverride` prop, which accepts a `ReactNode`, and the background color can be customized with the `style` prop or `className` prop.

**Note**: when customizing any Design System component, please first consult with your team's design lead to ensure that the customization is in line with the Design System guidelines.

```jsx
<MessageBlock.Root
  iconOverride={<Briefcase />}
  style={{
    "--icon-color": "var(--ds-semantic-color-background-accent-orange)",
    backgroundColor: "var(--ds-components-chip-color-background-orange-subtle)",
    borderColor: "var(--ds-semantic-color-border-accent-orange)",
  }}
>
  <MessageBlock.Title>Custom Title</MessageBlock.Title>
  Content on a custom background color.
</MessageBlock.Root>
```

| render | `DOMRenderFunction<"h1", undefined>` | - | Overrides the default DOM element with a custom render function. This allows rendering existing components with built-in styles and behaviors such as router links, animation libraries, and pre-styled components.&#xA;&#xA;Requirements:&#xA;&#xA;- You must render the expected element type (e.g. if \`\<button>\` is expected, you cannot render an \`\<a>\`).&#xA;- Only a single root DOM element can be rendered (no fragments).&#xA;- You must pass through props and ref to the underlying DOM element, merging with your own prop as appropriate. |
