      ```tsx lines expandable theme={null}
      import { Alert } from "@servicetitan/anvil2";

      function App() {
        return (
          <Alert status="warning" title="Alert Warning">
            Warning message
          </Alert>
        );
      }

      export default App;
      ```
    </LiveCode>

    ## Common Examples

    ```tsx theme={null}
    import { Alert } from "@servicetitan/anvil2";

    function ExampleComponent() {
      return (
        <Alert status="warning" title="Warning!">
          This is a warning message.
        </Alert>
      );
    }
    ```

    ### Alert statuses

    Use the `status` prop to set the color and icon of the `Alert`.

    <LiveCode showCode example="alert-status" screenshot fullWidth>
      ```tsx lines expandable theme={null}
      import { Alert, Flex } from "@servicetitan/anvil2";

      function App() {
        return (
          <Flex direction="column" gap="4" flex="1">
            <Alert title="Info Alert" onClose={() => console.log("info onClose")} />
            <Alert
              title="Success Alert"
              status="success"
              onClose={() => console.log("success onClose")}
            />
            <Alert
              title="Warning Alert"
              status="warning"
              onClose={() => console.log("warning onClose")}
            />
            <Alert
              title="Danger Alert"
              status="danger"
              onClose={() => console.log("danger onClose")}
            />
          </Flex>
        );
      }

      export default App;
      ```
    </LiveCode>

    ### Closable alerts

    Make an alert closable by providing a value to the `onClose` prop.

    <LiveCode showCode example="alert-onclose" screenshot fullWidth>
      ```tsx lines expandable theme={null}
      import { Alert, Flex, Button } from "@servicetitan/anvil2";
      import { useState } from "react";

      function App() {
        const [isOpen, setIsOpen] = useState(true);

        return (
          <Flex direction="column" gap="4" flex="1">
            {isOpen ? (
              <Alert title="Closeable Alert" onClose={() => setIsOpen(false)} />
            ) : (
              <Button
                size="large"
                onClick={() => setIsOpen(true)}
                style={{ width: "100%" }}
              >
                Open Alert
              </Button>
            )}

            <Alert title="Alert without onClose" />
          </Flex>
        );
      }

      export default App;
      ```
    </LiveCode>

    ### Alerts with actions

    It is common to use Anvil2 [Buttons](/docs/web/components/button/design) within alerts to create actions. These can easily be arranged using the [Flex](/docs/web/components/flex/code) component.

    <LiveCode showCode example="alert-button" screenshot fullWidth>
      ```tsx lines expandable theme={null}
      import { Alert, Text, Flex, Button } from "@servicetitan/anvil2";

      function App() {
        return (
          <Alert status="danger" title="Problem loading data">
            <Text>
              There was an error loading the page data. Please refresh the page.
            </Text>
            <Flex gap={4}>
              <Button>Refresh Page</Button>
              <Button>Message Support</Button>
            </Flex>
          </Alert>
        );
      }

      export default App;
      ```
    </LiveCode>

    ### AI Mark

    Add an [AI Mark](/docs/web/components/ai-mark/code) inline after the alert title by passing `aiMark`. Use `true` for the sparkle only, or pass tooltip or popover configuration.

    <LiveCode showCode example="ai-mark-alert" screenshot fullWidth>
      ```tsx lines expandable theme={null}
      import { Alert } from "@servicetitan/anvil2";

      function App() {
        return (
          <Alert
            title="Suggested upsell"
            status="info"
            aiMark
            style={{ maxWidth: "550px" }}
          >
            Customer asked about indoor air quality—consider adding a media filter
            upgrade and UV option to this HVAC maintenance estimate.
          </Alert>
        );
      }

      export default App;
      ```
    </LiveCode>
  </Tab>

  <Tab title="Alert Props">
    ```tsx theme={null}
    <Alert
      title="Warning!"
      status="warning"
      onClose={(e) => console.log("Alert closed")}
    >
      This is a warning message.
    </Alert>
    ```

    ## `Alert` Props

    <ParamField path="title" type="string" required />

    <ParamField path="aiMark" type={`boolean | AiMarkWithTooltipOrPopoverConfig`}>
      When set, displays the AI mark inline after the title. Use `true` for the sparkle only, or pass tooltip or popover configuration. See [AI Mark](/docs/web/components/ai-mark/code).
    </ParamField>

    <ParamField path="onClose" type="(e: MouseEvent) => void">
      The component is closeable if this prop is provided.
    </ParamField>

    <ParamField path="status" type={`"info" | "success" | "warning" | "danger"`} default="info" />
  </Tab>
