The nodes in the "dendrogram" category have two modes available: Transform and Exposed Inputs.
Transform Nodes
Transform mode is the default for Dendrogram nodes. A T connector is included on the node, and a matching Transform node connects to it.
Why use the Transform?
The Transform mode requires an additional Transform input node, which automatically adds all of the required properties to the Dendrogram node. Transform Nodes are an easy way to publish all settings in a single click.
For instance, the Site Fill transform node automatically adds these 3 properties to the properties palette:
Transform nodes often also include UI widgets like sliders or list managers to make it easier to edit the flow results. For instance, the along point transform:
Editing Default Values
You can also edit the defaults so every time the flow is re-used, it starts with the same assumptions. In the Flow Canvas, click "Edit Defaults" on the Transform Node.
A preview of the properties appears on the left-hand side as an overlay.
Create a custom header for the node properties in the properties palette.
By default, the header will say the name of the node the transform pairs with - ie "Site Fill."
You can change this to be any custom value to make it easier for end users to know what the settings are for.
This can be especially useful in nested flows that re-use the same nodes for different sections or controls.
Publish the properties with a toggle
If the toggle is on, the transform properties will display in the properties palette
If the toggle is off, the properties will be hidden and always use the defaults set in the "edit defaults" canvas
The Transform Default values
Edit the default values for the flow.
Any new instances of the flow will automatically inherit these defaults.
Any changes in the properties palette will override the transform defaults.
Expose Inputs Mode
Swap between Transform Mode and Expose Inputs with the pet menu. Right Click on a selected dendrogram node, and select "Expose Inputs."
Why Use Exposed Inputs?
With Inputs exposed, each property or input value that was previously handled with the Transform as now embedded into the node. This makes the dendrogram nodes behave more similarly to other (simpler) nodes in the Flow Builder node library.
In Exposed Inputs mode, you can:
Type values directly into text boxes/number spinners on the node to "hard code" the settings.
Add Input parameters to expose certain properties to the property palette UI, while leaving others hidden.
Give the Input parameters custom names to clarify detailed flow logic in the properties palette UI.
Control input values with outputs from other nodes without using write property as a go-between in the transform node.
Swap Between Modes
You can quickly swap between modes using the pet menu.
However, the Transforms & Input Parameters do not convert between modes.
It is best to select the mode you want to use and stick with it as part of your flow design.
Comparing Transform vs Exposed Inputs Modes
There is no right or wrong method for your flows. Most will simply use the default Transform mode as it is the fastest and most consistent way to control the node inputs. The Exposed Inputs mode is available for advanced editors and flow masters who need more control.
