Adding a child-node is very simple. Just hover your cursor over the main dialog node and click the more option.
You’ll be able to see the Add a Child Node option pop up. Click it again to add a child node. A child-node allows you to set if conditions within a dialog flow.
The child node can be thought of as creating a new dialog altogether using intents, entities, and variables.
For example: You can make the Assistant provide user with options for resetting a password or unlocking an account. And you can create separate child nodes for resetting a password and as well as for unlocking an account by leaving the Create Child Nodes button switched on, on the Options pop up. when a user selects an option, the respective child node gets executed.
If you accidently switched off the Create Child Nodes button, then you can manually create the child nodes with the Add Child node option.
Child nodes allow you to set if conditions effortlessly.
You can test your dialog flow as you go about building it. Check the next section to learn how you can do so.
