### Repeating rows and the Dashboard special data source
|
||||
|
||||
If a row includes panels using the special [Dashboard]({{< relref "../../../datasources/#special-data-sources" >}}) data source—the data source that uses a result set from another panel in the same dashboard—then corresponding panels in repeated rows will reference the panel in the original row, not the ones in the repeated rows.
|
||||
|
||||
For example, in a dashboard:
|
||||
|
||||
- `Row 1` includes `Panel 1A` and `Panel 1B`
|
||||
- `Panel 1B` uses the results from `Panel 1A` by way of the `-- Dashboard --` data source
|
||||
- Repeating row, `Row 2`, includes `Panel 2A` and `Panel 2B`
|
||||
- `Panel 2B` references `Panel 1A`, not `Panel 2A`

## Configure repeating panels
|
||||
|
||||
You can configure Grafana to dynamically add panels or rows to a dashboard. A dynamic panel is a panel that the system creates based on the value of a variable. Variables dynamically change your queries across all panels in a dashboard. For more information about repeating rows, refer to [Configure repeating rows](../add-organize-panels/#configure-repeating-rows).

Repeating panels require variables to have one or more items selected; you cannot repeat a panel zero times to hide it.
