# Drill-down

> Click a mark for a menu of actions on that value — see the rows behind it, drill into a finer dimension, or open it as a sheet.

A single value in a result or chart is an aggregate of many rows. Drill-down lets
you click that value to see the rows behind it, or to break it down by a finer
dimension — moving from "what" to "why" without rebuilding the query.

## Clicking a mark

When you click a mark — a bar, a line point, a pie slice, or a table cell — Flax
reads what you clicked: the series and the category value that identify that point.
It maps those back to the model's fields and builds filters for exactly that slice,
keeping the filters already on the query.

A menu opens at your cursor, headed by the value you clicked, offering everything
you can do with it: filter the dashboard to it, drill to detail, open it as a sheet,
or ask the AI about it. Right-clicking or tapping opens the same menu — no gesture
acts on its own, and the arrow keys reach the marks without a mouse (see
[Interactivity](/docs/visualizations/interactivity)). Choosing **Drill to detail** opens
a **Drill** modal showing:

- **Applied-filter chips** describing the slice you drilled into.
- The **underlying rows** for that slice, fetched ungrouped (up to a 1,000-row
  cap), which you can **export to CSV** or **open in a sheet** to keep working with
  (see [View in sheet](/docs/exploring/view-in-sheet)).

Time-bucketed clicks filter on the whole bucket — for example, clicking a monthly
bar filters to that month at the dimension's grain.

## Drilling into a finer dimension

If the clicked dimension declares a child in the model (for example
country → city, or an implicit month → day for time), the modal offers a
**Drill into** button naming that child. Choosing it rewrites the query in place: it swaps the
clicked dimension for its child, adds the clicked value as a filter, and re-runs.

A **Drilled** breadcrumb of chips shows where you are, and a **Clear** button
returns to the original query.

## On dashboards

Drill-down works from dashboard tiles too, and each tile drills independently with
its own breadcrumb, so a summarized dashboard becomes a starting point for
investigation. See [Interactivity](/docs/visualizations/interactivity) for
dashboard drilling and cross-filtering.

> [!NOTE]
> Drill-down respects the same [row-access filters](/docs/modeling/row-access-filters)
