Drill-down allows you to further break down data within your scenario to gain a more granular view. By setting a drill-down dimension, you essentially add a secondary grouping to the data under your primary group. For example, if your chart displays sales by year, adding a drill-down could break a specific year’s data into sales by product category for that year.
Drill-down functionality is configured in the Data Binding Tab. You need to select the mode as either Pre-set Targetsor Pre-set Path, which enables the corresponding data binding slot: Drill Down Targets or Drill Down Path.
When using Pre-set Targets, clicking on a data point in preview opens a context menu with your pre-set target dimensions. Selecting a dimension breaks down the data point by that dimension. For example, clicking a year could let you choose to break it down by Product Category or Region.

Pre-set Paths behave differently. Clicking a data point in preview automatically drills down by the pre-set dimension. If multiple dimensions are configured, clicking the data point repeatedly will drill down further through the defined path.

You can customize drill-down behavior via the Inspector Panel, particularly the breadcrumb menu that appears once you drill down.
The Position property sets where the breadcrumb menu appears on the scenario. Default is Top Left, but it can also be set to Top Center, Top Right, Bottom Left, Bottom Center, or Bottom Right.
Home Name refers to the first item in the breadcrumb menu—the original view without any drill-down. It is automatically labeled "Home," but you can provide a custom name.
You can customize the appearance of the breadcrumb menu using the following font-related properties:
Font family
Font size
Font weight
Font style (italic or normal)
These settings ensure the breadcrumb menu remains readable and visually consistent with the dashboard.
The breadcrumb menu font is interactive. Current Level Font Color sets the color of the currently selected drill-down item (e.g., if you click 2018, that year will appear in this color). Other Levels Font Color sets the color of the remaining items in the breadcrumb menu that are not currently selected.
