          </Overflow>
        );
      }

      export default App;
      ```
    </LiveCode>

    ## Common Examples

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

    function ExampleComponent() {
      return (
        <Overflow truncate height="5rem">
          {/* Overflow Content */}
        </Overflow>
      );
    }
    ```

    ### Overflow any elements

    By default, the `Overflow` component creates a vertically scrolling area with a shadow to indicate which directions it can be scrolled.

    <LiveCode showCode example="overflow-direction-column" screenshot fullWidth>
      ```tsx lines expandable theme={null}
      import { Overflow, Card, Text } from "@servicetitan/anvil2";

      function App() {
        return (
          <Overflow gap="4" height={200}>
            {[0, 1, 2, 3, 4, 5, 6, 7, 8, 9].map((i) => (
              <Card
                key={i}
                justifyContent="center"
                alignItems="center"
                style={{ minWidth: 100, minHeight: 100 }}
              >
                <Text el="h4" variant="headline" size="xlarge">
                  {i + 1}
                </Text>
              </Card>
            ))}
          </Overflow>
        );
      }

      export default App;
      ```
    </LiveCode>

    #### Horizontal overflow

    To apply the overflow effect horizontally, add `direction="row"` to the `Overflow` component:

    <LiveCode showCode example="overflow-direction-row" screenshot fullWidth>
      ```tsx lines expandable theme={null}
      import { Overflow, Card, Text } from "@servicetitan/anvil2";

      function App() {
        return (
          <div style={{ maxWidth: "calc(100vw - 4rem)" }}>
            <Overflow direction="row" gap="4">
              {[
                0, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19,
              ].map((i) => (
                <Card
                  key={i}
                  justifyContent="center"
                  alignItems="center"
                  style={{ minWidth: 100, minHeight: 100 }}
                >
                  <Text el="h4" variant="headline" size="xlarge">
                    {i + 1}
                  </Text>
                </Card>
              ))}
            </Overflow>
          </div>
        );
      }

      export default App;
      ```
    </LiveCode>

    #### Overflow truncation

    To display a "Show more..." button, you can add the `truncate` prop. For more custom use cases, `truncate` can also accept an object to specify custom expand/collapse display text and custom event handlers.

    <LiveCode showCode example="overflow-truncate" screenshot fullWidth>
      ```tsx lines expandable theme={null}
      import { Overflow, Card, Text } from "@servicetitan/anvil2";

      function App() {
        return (
          <Overflow direction="column" gap="4" height={200} truncate>
            {[0, 1, 2, 3, 4, 5, 6, 7, 8, 9].map((i) => (
              <Card
                key={i}
                justifyContent="center"
                alignItems="center"
                style={{ minWidth: 100, minHeight: 100 }}
              >
                <Text el="h4" variant="headline" size="xlarge">
                  {i + 1}
                </Text>
              </Card>
            ))}
          </Overflow>
        );
      }

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

  <Tab title="Overflow Props">
    ```tsx theme={null}
    import { Overflow } from "@servicetitan/anvil2";

    function ExampleComponent() {
    return (

    <Overflow direction="column" height="5rem" width="100%" truncate={false}>
      {/* Overflow content */}
    </Overflow>
    ); }

    ```

    ## `Overflow` Props

    In addition to the props listed below, the `Overflow` component can accept any valid HTML `div` props:

    <ParamField path="direction" type="CSSProperties[flexDirection]" default="column">
      Accepts [CSS `flex-direction`](https://developer.mozilla.org/en-US/docs/Web/CSS/Reference/Properties/flex-direction) values.
    </ParamField>

    <ParamField path="height" type="number | string" />

    <ParamField path="truncate" type="boolean | { expandText?: string; collapseText?: string; onExpand?: (e: MouseEvent) => void; onCollapse?: (e: MouseEvent) => void }">
      The `truncate` prop can only be used with `direction` set to `"column"`.
    </ParamField>

    <ParamField path="width" type="number | string" />
  </Tab>
