Choice Block
What is a choice block
The choice card block is a type of choice block that presents users with one or more options that can be used to display additional information that will aid users in decision-making. This block enhances user interaction by allowing them to select their preferred option from either a predefined or dynamic list of options.
Types of choice blocks
There are two types of choice blocks:
Dynamic choice block
Dynamic cards are used to display real-time data. Instead of updating the data manually each time it changes, variables can be used to fetch and display the latest data whenever triggered. This ensures that the displayed information is always up to date without any extra effort.
You can choose one or more cards from a selection of dynamic cards. This can be done by choosing the Button Selection Type as Single Button or Multiple Button.
If customer choices are predefined, static info can be used. If the choices are dynamic and based on API responses, a dynamic choice block should be used.
Static choice block
The content of the field remains as you originally defined it when creating the block.This approach is particularly useful when you need to display a consistent message to all users.
Static choice blocks allow you to display a collection of items available for sale, automatically removing those that have sold out. Customers can select from the remaining options. By using static choice blocks, you ensure that every user sees the same consistent message and choice options. This feature can be used to display the full range of items.
Components of Card List ( Static choice block):
- Card name: Name of the card that will be displayed to the user.
- Image: An image appropriate to the card, title, and other details.
- Title: Title that best describes the information you intend to display in the card.
- Sub-title: Additional details can be showcased through adding a suitable sub-title.
- Description: A summarized context can be added here based on what needs to be relayed to the user.
- Add card field: Contains button and text. You can either add text or add a button that can be redirected to a different webpage.
The fields you don't require to be displayed in the card can be deleted, with one exceptional case of title that is mandatory. If you need to add it to the next card, you can find those deleted fields in the add card field dropdown.
You can add a button for redirecting the user to, for example, purchasing the displayed product or learning more about it.
Components of Card List (Dynamic choice block):
Advanced settings:
Common to every field except Image, you can use Value to add the content you require to display to the user. Label is an additional option through which you can add a text that describes the value.
For a card that involves an image, you can browse and add or drag the image. The size of the image cannot exceed the limit of 14 MB.
Adding Value will not be required here.You can choose to hide the Label if not required.
Why use the static choice block?
Using static cards in a chatbot for product information offers several advantages:
- Visual appeal: Makes the interaction more engaging and visually appealing.
- Call to action: Static cards can include buttons or links for actions like "Buy Now," "Learn More," or "Add to Cart," making it easier for users to take the next step without having to type additional commands.
- Enhanced context: Static cards can provide context about the product or the service provided by you in detail, helping them make an informed purchase.
- Efficient use of space: Static cards can efficiently use the limited space in a chat interface to provide rich information without overwhelming the user with too much text.

- If a change is made to an input variable, it will be updated across all flows where the variable is used automatically.
