Maximum of **three buttons allowed**.

#### Variables: <a href="#variables" id="variables"></a>

Variables are used to store the input received from the visitor, so you can reference it for later use.

You can either choose an existing variable from the dropdown or create a new one.

Only Branch button selection made by the visitor will be stored in the variable.

[Learn more about variables here.](/wotsabot-help-articles/variables.md)

#### Example: <a href="#example" id="example"></a>

Imagine you are building a chatbot to showcase the properties offered in your real estate company.

You can use Carousel to display all the properties offered by you with an image, name of property and details of some amenities offered.

And the buttons can be:

* **Learn more** -- which redirects to your webpage with more details.
* **Book a visit** -- which continues the flow asking for contact info to book a site visit.
