# Panel Linking

Using panel linking you can link any of your [panels](/panels.md) to either update its data or add new data to it from within any survey form. 

Once linked to a survey the [panel attributes](/panels/untitled.md) will be made available as a question that you can move anywhere inside the form as you would with any normal [question](/form-management/form-designer/questions.md).

Linked panels can be useful in following use cases.

* [**Panel auto filling**](/form-management/form-designer/questions/panel-linking/panel-auto-filling.md) to add a new panelists on the go based on new respondent answers.
* [**Panel updating**](/form-management/form-designer/questions/panel-linking/panel-updating.md) to let respondents update pre-existing panel data from within a survey.

## 👪 Linking a panel to your form 

To link a panel you need to **insert a new question** and chose the **Panel question** type. This will open a wizard to chose the panel you would like to use in your survey form.

The respondent will now either be able to [add new panelist](/form-management/form-designer/questions/panel-linking/panel-auto-filling.md) using that linked question or [update ](/form-management/form-designer/questions/panel-linking/panel-updating.md)pre-existing panelist data.

## 🔅 Panel attribute link properties 

You may also configure each [panel attribute](/panels/untitled.md) behavior from the [panel attributes properties](/panels/untitled.md) to make a  it read only, visible, updatable depending if the linked panel question is used for [panel filling](/form-management/form-designer/questions/panel-linking/panel-auto-filling.md) or [panel updating](/form-management/form-designer/questions/panel-linking/panel-updating.md).
