Build Child Nodes · Stella Platform Documentation

Let's continue to follow the tree diagram to build the remaining child nodes and you are very close to completing your first chatbot!

Sample tree diagram

Child Nodes are the nodes that come after the first node and they can be in the second layer, the third layer or even the layers after. Users cannot access any Child Node if they are not on the designated path.

In the above example, "Opening Hours message" is the Child Node of "Do you want to check out the opening hours or shop address?" and can only be triggered when user clicks "Opening Hours".
