+
+**Canvas** lets users work with generated or editable content alongside a conversation. Canvas content is fully flexible, allowing you to render any content suitable for your use case. It is recommended to only utilize canvas mode with a fullscreen Chatbot.
+
+## Composable structure
+
+When utilizing a canvas layout, it's recommended to use a PatternFly [drawer](/components/drawer). You must apply the `pf-chatbot__canvas*` classes from `@patternfly/chatbot` so the drawer matches ChatBot backgrounds and fills the fullscreen layout.
+
+The general recommended structure is as follows:
+
+```noLive
+<Chatbot displayMode={ChatbotDisplayMode.fullscreen}>
+  <div className="pf-chatbot__canvas">
+    <Drawer className="pf-chatbot__canvas-drawer" isExpanded={...} isInline position="end">
+      <DrawerContent panelContent={/* CodeEditor or other canvas content */}>
+        <DrawerContentBody className="pf-chatbot__canvas-body">
+          <div className="pf-chatbot__canvas-column">
+            <ChatbotHeader .../>
+            <ChatbotContent ... />
+            <ChatbotFooter ... >
+          </div>
+        </DrawerContentBody>
+      </DrawerContent>
+    </Drawer>
+  </div>
+</Chatbot>
+```
+
+## Class names
+
+| Class name | Purpose |
+| --- | --- |
+| `pf-chatbot__canvas` | Container for the fullscreen canvas layout and its background. |
+| `pf-chatbot__canvas-drawer` | Styles the drawer that contains the canvas panel. |
+| `pf-chatbot__canvas-section` | Styles the section used within the drawer for focus. |
+| `pf-chatbot__canvas-body` | Ensures the drawer content body fills the available height. |
+| `pf-chatbot__canvas-column` | Arranges the canvas header, content, and footer vertically. |
+| `pf-chatbot__canvas-panel` | Styles the canvas drawer panel and removes the default panel spacing. |
+| `pf-chatbot__canvas-panel-body` | Provides the canvas panel content area and its spacing. |
+| `pf-chatbot__canvas-head` | Styles and positions the canvas panel header and close action. |
+| `pf-chatbot__canvas-editor` | Makes the code editor fill the available canvas space. |
+
+## Demos
+
+### With code editor
+
+This demo shows canvas mode being used to render a PatternFly [code editor](/components/code-editor). Canvas mode is launched by clicking a file chip below a message or the "Canvas" label below the message bar. You can also enable or disable canvas mode from the attach menu and dismiss the label to exit canvas mode.

+```js file="./Canvas.tsx" isFullscreen
