# ActionLog – Design

> Action logs surface a chronological record of agent and system activity.

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

  export default App;
  ```
</LiveCode>

## Options

The Action Log supports step statuses, optional descriptions, and per-step expandable details.

### Statuses

<LiveCode example="carto-action-log-statuses" screenshot fullWidth>
  ```tsx lines theme={null}
  import { ActionLog } from "@servicetitan/carto-react-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>

Four statuses mark each step: success, in-progress, not-started, and error. The error status uses a distinct red to signal a failed step; all others render in the neutral foreground.

| Status      | When to use                         |
| ----------- | ----------------------------------- |
| Success     | The step completed without issues   |
| In Progress | The step is actively running        |
| Not Started | The step is queued but hasn't begun |
| Error       | The step failed and halted the run  |

### Descriptions

<LiveCode example="carto-action-log-descriptions" screenshot fullWidth>
  ```tsx lines theme={null}
  import { ActionLog } from "@servicetitan/carto-react-kit";

  function App() {
    return (
      <ActionLog
        steps={[
          {
            id: "a",
            title: "Pulled the last 20 invoices",
            status: "success",
            description: "Found 3 overdue invoices totaling $1,240.",
          },
          {
            id: "b",
            title: "Drafting the follow-up summary",
            status: "in-progress",
            description:
              "Summarizing overdue balances and recent payment history.",
          },
          {
            id: "c",
            title: "Couldn't reach the billing service",
            status: "error",
            description: "Timed out after 30s; the run was halted.",
          },
        ]}
      />
    );
  }

  export default App;
  ```
</LiveCode>

An optional description renders below the step title as body text, providing additional context about what the step found or did. When descriptions are present, the connector line between steps spans a taller area, making the timeline easier to scan. Apply descriptions consistently across a log — mixing steps with and without descriptions creates an uneven vertical rhythm.

### Details

<LiveCode example="carto-action-log-details" screenshot fullWidth>
  ```tsx lines theme={null}
  import { ActionLog, Text } from "@servicetitan/carto-react-kit";

  const detailsContent = (
    <Text
      variant="body"
      size="compact"
      text="Overdue since April · last payment May 3 · $1,240 across 3 invoices."
    />
  );

  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: "Drafting the follow-up summary",
      status: "in-progress" as const,
      description: "Summarizing overdue balances and recent payment history.",
      details: detailsContent,
    },
    {
      id: "c",
      title: "Send the summary to the customer",
      status: "not-started" as const,
    },
  ];

  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>

A step with a `details` value gains an independent "Show details" disclosure. The details content renders inside a Card below the description and is collapsed by default, keeping the log compact while allowing deeper inspection on demand.

## Behavior

The Action Log uses two levels of disclosure: one for the entire step list and one per step that has details content.

### Expand and Collapse

<LiveCode example="carto-action-log-expand-and-collapse" screenshot fullWidth>
  ```tsx lines theme={null}
  import { ActionLog } from "@servicetitan/carto-react-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>

The whole log starts expanded and collapses behind a "Show steps" / "Hide steps" toggle. Collapsing the log hides all step rows but preserves the expanded or collapsed state of any individual details disclosures.

### Overflow

<LiveCode example="carto-action-log-overflow" screenshot fullWidth>
  ```tsx lines theme={null}
  import { ActionLog } from "@servicetitan/carto-react-kit";

  function App() {
    return (
      <div style={{ maxWidth: "20rem" }}>
        <ActionLog
          steps={[
            {
              id: "a",
              title:
                "Reconciled every line item on Invoice #37482915 against the signed service agreement",
              status: "success",
              description:
                "Compared parts, labor, and adjuster notes line by line, then flagged three entries that didn't match the agreed scope of work for a human to review.",
            },
          ]}
        />
      </div>
    );
  }

  export default App;
  ```
</LiveCode>

Long titles and descriptions wrap to multiple lines within the content column. The connector line extends to match the full height of each step, regardless of how much text wraps.

## Keyboard Interaction

Users can navigate and operate the Action Log using standard keyboard controls.

| Key           | Description                                   |
| ------------- | --------------------------------------------- |
| Tab           | Moves focus to the next disclosure trigger    |
| Enter / Space | Toggles the focused disclosure open or closed |
