# Drill-ins

> Use drill-ins to expand a driver row and inspect the inputs that contribute to its values.

Drill-ins let you inspect what contributes to a driver without leaving the table. Use them when you want to trace a formula, understand a variance, or show the rows and drivers behind a modeled number.

## How to use drill-ins

<Steps>
  <Step title="Choose a driver">
    In a driver table, hover over a driver row that can be expanded. A caret appears next to eligible rows.
  </Step>

  <Step title="Open inputs">
    Click the caret next to the driver name, or right-click the driver and select **Show inputs**. You can also press `⌘⏎` (`Ctrl+Enter` on Windows) on the selected row.
  </Step>

  <Step title="Review the inputs">
    The driver's inputs appear as nested child rows. Drilling into dimensional or database-backed drivers expands segment and object sub-rows, and you can keep drilling into eligible child rows.
  </Step>

  <Step title="Close inputs">
    Click the caret again, right-click the driver and select **Hide inputs**, or press `⌘⏎` (`Ctrl+Enter` on Windows) again.
  </Step>
</Steps>

<Tip>
  Drill-ins support multiple levels of depth. Expand an input line further to inspect its dependencies.

## Drill-in access

Drill-ins respect the block-level **Can drill in** access rule. For current access rules, see [Permissions](/guides/sharing/permissions) and [Roles and access](/reference/roles-and-access).

## Open detail view

Use **Open detail view** or press `⌘⇧⏎` (`Ctrl+Shift+Enter` on Windows) to open the details pane for the selected row. The details pane shows **Overview**, **Used By**, and **Plans** tabs when available. See [Driver details pane](/concepts/drivers/driver-details-pane) for more detail.

## Important notes

### Drill-ins are saved per user

Expanding drill-ins affects your own view. Other users do not see the expanded state unless they expand the row themselves.

### Want others to see a breakdown?

If you want other users to view the same rows, add selected drill-in drivers to the block from the row context menu. This makes those driver lines visible in the block instead of depending on each user's expanded drill-in state.

### Drill-in lines have a striped background

Stripes indicate drill-in lines are dynamically generated and will not appear for other users unless expanded.

<Warning>
  Drag-and-drop reordering and undo/redo are not supported for drill-in lines.
