General Node Usage

Creating a Node

Flow Nodes can be used to add interactivity to a Flow. When combined in a certain way, they can help create dynamic interactive conversations. There are many types of Nodes, ranging from Basic to Advanced.

Nodes can be created by clicking on the + icon in a Flow, after which the Node selection menu appears.

A Node can be copied by right-clicking it and pasted by right-clicking on a + section in the Flow.

Removing a Node

To remove a Node you can either delete or cut it. If you choose to cut the Node, you can paste it at the location of your choice (see "Paste a Node" below). If you delete it, it is gone but can be restored by reverting the change. Removing a Node also removes all of its child Nodes.

Flow Editor Hotkeys

For a full list of flow editor keyboard shortcuts, see the Hotkeys Page.

Copy a Node

You can copy a Node with the corresponding menu option. This also copies all child Nodes (e.g. all the Case and Default Nodes and their children, if you copy a Lookup Node).

Drag & Drop

The flow editor supports drag and drop within the flow editor. To copy a node, simply hold the alt key while dropping the node to the required location.

Add Comment

You can add additional information about Nodes in the Node Comment. To add a comment, open a Node by clicking on on it and scroll down to the Styling section. Here you can add a comment.

Add Label

Adding a Label replaces the bottom text line of a Node. This allows you to have a Node functionality summary that is directly visible in the Flow editor. You can change the Label by opening a Node and scrolling down to the Styling section.

Set Entrypoint

Any flow node can be added as an entrypoint for the flow. This means that a Go To Node or an Execute Flow Node can be set to start directly at any node. The Start Node is the default entrypoint for the flow and both Question Nodes and Optional Question Nodes will be automatically assigned as an optional entrypoint when they are added.

Any other node can be manually assigned as a flow entrypoint by opening the node editing menu and selecting the three dot menu from the top right hand corner. The option to "Set Entrypoint" can be selected which will add this node to the list of available entrypoints.

Naming Entrypoints

It is helpful to define unique names for each entry point node using the label feature. This means that users will be able to easily differentiate when selecting them from a list of options. For example, all Question nodes will be called "Question" unless the label is manually adjusted.

Warning

Version badge

As of release v4.8 a warning message will be displayed in case your Flow includes more than 100 nodes:

  • If you create a flow including more than 100 nodes you will get a warning.
  • If you open an existing flow with more than 100 nodes you will get this warning.
  • The error should disappear if you remove some nodes and sink below 100.
  • You can disable the notification in your profile settings.
Warning information - Nodes > 100

Node ID

Version badge

As of release Cognigy.AI (4.10.0), Cognigy.AI provides Node IDs in every Flow. Navigating such URL opens the sidebar and scrolls the viewport to the Node.

In detail:

  • Clicking on a Node in the Flow Chart adds its ID to the URL.
  • Closing the sidebar removes the ID from the URL.
  • Opening the page containing Node ID will open the sidebar and center the viewport on the Node.
