# Groups

Groups can be added like any other question, just drag the group question into your form:

![](/files/lBjxFGw9suY8UOtFzOI4)

Once dropped, type the group header (required) and click "Edit Group" to enter the group editing mode:

![](/files/8gUjQmApvvUvxN3cN03s)

{% hint style="warning" %}
**You MUST type a header to enable the edit button!**
{% endhint %}

In group edit mode, just drag any input as usual. You **CANNOT** have a group within a group. You can have branches though.

{% hint style="warning" %}
A group MUST have at least one question to be valid.
{% endhint %}

{% hint style="warning" %}
Moreover, you **CANNOT** have JUMP(s) within a GROUP.
{% endhint %}

To exit the group edit mode, click the left arrow on the top left, to go back to the usual hierarchy form editing:

![](/files/pfSvbuoemtcEwqqBi70O)

Using GROUP(s) it is possible to add matrix style questions to your form(s). [**See how**](/common-use-cases/matrix.md)**.**
