Node Drawer is the top section located right below the Tree Manager blue bar. It acts as a storeroom of all your created nodes. Within a chatbot structure, there are two types of node: Node and Global Node.
All the nodes you have created, both active and inactive, will be put under the rows of Node and Global Node respectively. You can just drag directly from the drawer to the workspace if you want to use the specific node.
A Node is a message response that can only be triggered following the designated path and trigger. A chatbot is basically a combination of nodes.
A Global Node is derived from Node and is a message response that can be triggered in anywhere within the conversation flow, i.e. users don't necessarily need to follow the the designated path or trigger to receive the message.
Global node is often used in the following situations:
- You want to set up different URL parameters which all lead to the same destination
- You want to allow certain buttons to be clicked repeatedly
- You want to put that button on the persistent menu
You can drag any node from the row of Node to the other row to turn it into a global node.
If a message is not set as a global node, users will not be able to trigger it without following the designated path. Global node is a must for actions that can be taken at anytime.
