# Panels
Panels are the main building blocks of dashboards.
## Panel development
### Scrolling
The grafana dashboard framework controls the panel height. To enable a scrollbar within the panel the PanelCtrl needs to set the scrollable static variable:
```javascript
export class MyPanelCtrl extends PanelCtrl {
static scrollable = true;
...
```
In this case, make sure the template has a single `<div>...</div>` root. The plugin loader will modify that element adding a scrollbar.
### Examples
- [clock-panel](https://github.com/grafana/clock-panel)
- [singlestat-panel](https://github.com/grafana/grafana/tree/master/public/app/plugins/panel/singlestat)
