  import { Text, Window } from "@servicetitan/carto-react-kit";

  function App() {
    return (
      <div style={{ position: "fixed", inset: 0, background: "#e9ecf1" }}>
        <Window
          chat={

          }
        />
      </div>
    );
  }

  export default App;
  ```
</LiveCode>

## Options

Window owns the same slots as [AppShell](/docs/kits/ai-kit/components/app-shell/design) — `header` and `chat` (shown in both states), plus `rail` and `artifact` (fullscreen only) — and presents them in one of two sizes.

### Window States

<LiveCode example="carto-window-window-states" screenshot fullWidth>
  ```tsx lines theme={null}
  import {
    AppHeader,
    CartoTheme,
    Text,
    Window,
    useAppSurface,
  } from "@servicetitan/carto-react-kit";
  import { IconMinimize2, IconX } from "@servicetitan/carto-react-kit/icons";
  import "@servicetitan/carto-react-kit/styles.css";

  function WindowHeader() {
    const { toggleSize, close } = useAppSurface();
    return (
      <AppHeader
        title="Title of conversation"
        trailingActions={[
          {
            id: "size",
            icon: <IconMinimize2 />,
            label: "Restore",
            onPress: toggleSize,
          },
          { id: "close", icon: <IconX />, label: "Close", onPress: close },
        ]}
      />
    );
  }

  function App() {
    return (
      <CartoTheme>
        <div style={{ position: "fixed", inset: 0, background: "#e9ecf1" }}>
          <Window
            defaultState="fullscreen"
            header={<WindowHeader />}
            chat={
              <div
                style={{
                  display: "flex",
                  alignItems: "center",
                  justifyContent: "center",
                  height: "100%",
                }}
              >
                <Text text="Chat content" />
              </div>
            }
          />
        </div>
      </CartoTheme>
    );
  }

  export default App;
  ```
</LiveCode>

**Docked** (shown above) is a fixed-size floating panel — header + chat, anchored bottom-right by default — that sits non-modally over the rest of the page. **Fullscreen** (shown here) is a modal takeover revealing the full `AppShell`: header, rail, chat, and artifact, over a scrim, with focus trapped inside. The `header` and `chat` nodes are the same React instance in both states — same DOM, scroll position, and in-flight state — so expanding or restoring never resets the conversation.

### Open Control

<LiveCode example="carto-window-open-control" screenshot fullWidth>
  ```tsx lines theme={null}
  import { useRef } from "react";
  import {
    AppHeader,
    Button,
    CartoTheme,
    Text,
    Window,
    useAppSurface,
  } from "@servicetitan/carto-react-kit";
  import type { AppSurfaceHandle } from "@servicetitan/carto-react-kit";
  import { IconMaximize2, IconX } from "@servicetitan/carto-react-kit/icons";
  import "@servicetitan/carto-react-kit/styles.css";

  function WindowHeader() {
    const { toggleSize, close } = useAppSurface();
    return (
      <AppHeader
        title="Title of conversation"
        trailingActions={[
          {
            id: "size",
            icon: <IconMaximize2 />,
            label: "Maximize",
            onPress: toggleSize,
          },
          { id: "close", icon: <IconX />, label: "Close", onPress: close },
        ]}
      />
    );
  }

  function App() {
    const ctrl = useRef<AppSurfaceHandle>(null);

    return (
      <CartoTheme>
        <div style={{ position: "fixed", inset: 0, background: "#e9ecf1" }}>
          <div style={{ position: "fixed", top: 24, left: 24 }}>
            <Button label="Open chat" onPress={() => ctrl.current?.open()} />
          </div>
          <Window
            controlRef={ctrl}
            header={<WindowHeader />}
            chat={
              <div
                style={{
                  display: "flex",
                  alignItems: "center",
                  justifyContent: "center",
                  height: "100%",
                }}
              >
                <Text text="Chat content" />
              </div>
            }
          />
        </div>
      </CartoTheme>
    );
  }

  export default App;
  ```
</LiveCode>

Open/close and docked/fullscreen work uncontrolled by default (seeded by `defaultOpen` / `defaultState`), or controlled by passing `open` / `state` alongside `onOpenChange` / `onStateChange` so an external store can be the source of truth. Either way, drive the same transitions imperatively via the `AppSurfaceHandle` — from a parent through `controlRef` (as shown here, with an external launcher button), or from inside the window (a header button, or a card in the chat) via `useAppSurface()`.

## Behavior

Both states share one surface, so the panel animates between them, and the docked panel can be repositioned.

### Maximize and Restore

<LiveCode example="carto-window-maximize-and-restore" screenshot fullWidth>
  ```tsx lines theme={null}
  import {
    AppHeader,
    CartoTheme,
    Text,
    Window,
    useAppSurface,
  } from "@servicetitan/carto-react-kit";
  import { IconMaximize2, IconX } from "@servicetitan/carto-react-kit/icons";
  import "@servicetitan/carto-react-kit/styles.css";

  function WindowHeader() {
    const { toggleSize, close } = useAppSurface();
    return (
      <AppHeader
        title="Title of conversation"
        trailingActions={[
          {
            id: "size",
            icon: <IconMaximize2 />,
            label: "Maximize",
            onPress: toggleSize,
          },
          { id: "close", icon: <IconX />, label: "Close", onPress: close },
        ]}
      />
    );
  }

  function App() {
    return (
      <CartoTheme>
        <div style={{ position: "fixed", inset: 0, background: "#e9ecf1" }}>
          <Window
            header={<WindowHeader />}
            chat={
              <div
                style={{
                  display: "flex",
                  alignItems: "center",
                  justifyContent: "center",
                  height: "100%",
                }}
              >
                <Text text="Chat content" />
              </div>
            }
          />
        </div>
      </CartoTheme>
    );
  }

  export default App;
  ```
</LiveCode>

The header's maximize control expands the docked panel into the fullscreen modal shell; restore (or Esc) shrinks it back. Docked and fullscreen share one surface, so the panel visibly grows and shrinks between the two rects rather than swapping instantly.

### Drag

<LiveCode example="carto-window-drag" screenshot fullWidth>
  ```tsx lines theme={null}
  import {
    AppHeader,
    CartoTheme,
    Text,
    Window,
    useAppSurface,
  } from "@servicetitan/carto-react-kit";
  import {
    IconGrip,
    IconMaximize2,
    IconX,
  } from "@servicetitan/carto-react-kit/icons";
  import "@servicetitan/carto-react-kit/styles.css";

  // A marker at the panel's default anchor (bottom-right, 24px inset — matching
  // the docked panel's own resting corner) so a screenshot of the dragged panel
  // still shows where it started, proving it moved.
  function DefaultCornerMarker() {
    return (
      <div
        style={{
          position: "fixed",
          insetBlockEnd: 24,
          insetInlineEnd: 24,
          width: 120,
          height: 48,
          border: "2px dashed #99a3ad",
          borderRadius: 8,
          display: "flex",
          alignItems: "center",
          justifyContent: "center",
        }}
      >
        <Text size="fine" text="Default corner" />
      </div>
    );
  }

  function WindowHeader() {
    const { toggleSize, close, dragHandleProps } = useAppSurface();
    return (
      <AppHeader
        title="Title of conversation"
        leadingActions={[
          {
            id: "drag",
            icon: <IconGrip />,
            label: "Move window",
            dragHandleProps,
          },
        ]}
        trailingActions={[
          {
            id: "size",
            icon: <IconMaximize2 />,
            label: "Maximize",
            onPress: toggleSize,
          },
          { id: "close", icon: <IconX />, label: "Close", onPress: close },
        ]}
      />
    );
  }

  function App() {
    return (
      <CartoTheme>
        <div style={{ position: "fixed", inset: 0, background: "#e9ecf1" }}>
          <DefaultCornerMarker />
          <Window
            header={<WindowHeader />}
            chat={
              <div
                style={{
                  display: "flex",
                  alignItems: "center",
                  justifyContent: "center",
                  height: "100%",
                }}
              >
                <Text text="Chat content" />
              </div>
            }
          />
        </div>
      </CartoTheme>
    );
  }

  export default App;
  ```
</LiveCode>

Docked, the panel is draggable: spread the surface's `dragHandleProps` (from `controlRef` / `useAppSurface()`) onto a leading header action — here an `IconGrip` — to turn it into a grip that moves the panel anywhere in the viewport. Arrow keys nudge it too, for keyboard users. The dragged position survives a maximize→restore round-trip (restore returns to it) and resets to the default corner only on close.

### Scrim Dismiss

Fullscreen is modal: a scrim sits behind the shell and dismisses back to docked on click, the same as pressing Esc. Because the shell fills the viewport, the scrim itself has no visible edge — the affordance is the dismissal, not a visible backdrop.

## Keyboard Interaction

Users can maximize, restore, move, and dismiss a window using standard keyboard controls.

| Key           | Description                                            |
| ------------- | ------------------------------------------------------ |
| Tab           | Moves focus among header actions and chat content      |
| Enter / Space | Activates the focused action                           |
| Arrow keys    | Moves the docked panel when the drag handle is focused |
| Escape        | Restores a fullscreen window to docked                 |
