# Action Log – Code

> The ActionLog presents a collapsible timeline of agent steps, statuses, descriptions, and details.

          />
        );
      }

      export default App;
      ```
    </LiveCode>

    ## Common Examples

    To use the `ActionLog`, pass configured steps through the required `steps` prop. Each step requires a stable `id` and a `title`.

    ```tsx theme={null}
    import { ActionLog } from "@servicetitan/anvil2-ai-kit";

    function ExampleComponent() {
      return (
        <ActionLog
          steps={[
            { id: "lookup", title: "Looked up the account", status: "success" },
            {
              id: "summary",
              title: "Drafting the summary",
              status: "in-progress",
            },
          ]}
        />
      );
    }
    ```

    ### Statuses

    `status` selects a neutral progress marker for `"not-started"`, `"in-progress"`, and `"success"`. `"error"` uses the critical treatment.

      ```tsx lines expandable theme={null}
      import { ActionLog } from "@servicetitan/anvil2-ai-kit";

      function App() {
        return (
          <ActionLog
            steps={[
              {
                id: "success",
                title: "Looked up the customer account",
                status: "success",
              },
              {
                id: "in-progress",
                title: "Drafting the follow-up summary",
                status: "in-progress",
              },
              {
                id: "not-started",
                title: "Send the summary to the customer",
                status: "not-started",
              },
              {
                id: "error",
                title: "Charge the saved card",
                status: "error",
              },
            ]}
          />
        );
      }

      export default App;
      ```
    </LiveCode>

    ### Descriptions and details

    Use `description` for supporting plain text. Use `details` for rendered content that appears inside an independently collapsible `Card`.

      ];

      function App() {
        return (
          <div
            style={{
              display: "flex",
              gap: 80,
              alignItems: "flex-start",
              padding: "24px 0",
            }}
          >
            {/* Details collapsed */}
            <div style={{ minWidth: 280 }}>
              <ActionLog steps={steps} />
            </div>

            {/* Details open */}
            <div style={{ minWidth: 280 }}>
              <ActionLog steps={steps} />
            </div>
          </div>
        );
      }

      export default App;
      ```
    </LiveCode>

    ### Expansion

    The step list starts expanded. Set `defaultExpanded={false}` to start collapsed. Each step's details remain independently controlled.

    <LiveCode showCode example="ai-kit-action-log-expand-and-collapse" screenshot fullWidth>
      ```tsx lines expandable theme={null}
      import { ActionLog } from "@servicetitan/anvil2-ai-kit";

      const steps = [
        {
          id: "a",
          title: "Looked up the customer account",
          status: "success" as const,
          description: "Retrieved account details and recent payment history.",
        },
        {
          id: "b",
          title: "Pulled the last 20 invoices",
          status: "success" as const,
          description: "Found 3 overdue invoices totaling $1,240.",
        },
        {
          id: "c",
          title: "Drafting the follow-up summary",
          status: "in-progress" as const,
          description: "Summarizing overdue balances and payment history.",
        },
      ];

      function App() {
        return (
          <div
            style={{
              display: "flex",
              gap: 80,
              alignItems: "flex-start",
              padding: "24px 0",
            }}
          >
            {/* Collapsed */}
            <div style={{ minWidth: 280 }}>
              <ActionLog defaultExpanded={false} steps={steps} />
            </div>

            {/* Expanded (default) */}
            <div style={{ minWidth: 280 }}>
              <ActionLog steps={steps} />
            </div>
          </div>
        );
      }

      export default App;
      ```
    </LiveCode>

    ### Heading level

    Set `titleLevel` to fit the surrounding document outline. The main steps toggle uses one level above it, and details toggles use one level below it. Step titles remain body text.

    ## Internationalization

    `ActionLog` owns these localized labels:

    * `ai-kit.actionLog.showSteps`
    * `ai-kit.actionLog.hideSteps`
    * `ai-kit.actionLog.showDetails`
    * `ai-kit.actionLog.hideDetails`
    * `ai-kit.actionLog.statusNotStarted`
    * `ai-kit.actionLog.statusInProgress`
    * `ai-kit.actionLog.statusSuccess`
    * `ai-kit.actionLog.statusError`

    Localize step titles and descriptions before passing them in `steps`. Mount `AiKitIntlProvider` inside `CartoTheme` to switch the built-in labels.

    ## React Accessibility

    * Status markers include localized screen-reader-only labels and do not imply form semantics.
    * The ordered list preserves step sequence.
    * Show steps, Hide steps, Show details, and Hide details expose disclosure state through accessible buttons.
    * Stable step `id` values preserve each details disclosure when steps stream or re-render.
