Hierarchy Browser Node (Tree) Component

This component is used within the Tree Browser Component.

For more information on how the hierarchy browser tree works, see the detailed explanation.

Function

a!hierarchyBrowserFieldTreeNode( id, label, description, details, image, link, isDrillable, nextLevelCount, showWhen )

Returns a Tree Node, used in the Node Configurations parameter of the Tree Browser Component to determine how items in the hierarchy are displayed.

Parameters

Name	Keyword	Types	Description
Identifier	id	Any Type	Required unique identifier of the node. This value only needs to be unique within the nodes level.
Label	label	Text	Required text to display in the node.

Node is drillable	isDrillable	Boolean	If true, clicking the node will drill into it, saving the tree browsers navigation path and revealing another level to the user. If false, clicking the node's will not reveal another level, but the navigation path will still be saved (default: true).
Next Level Count	nextLevelCount	Integer	Optional count of nodes that would be displayed in the next level were this node in the navigation path.
Visibility	showWhen	Boolean	Determines whether the component is displayed on the interface. When set to false the component is hidden and is not evaluated. Default: true.

Usage considerations

Drillable and non-drillable elements

You can see some of these terms and parameters labeled in the following screenshot.

Using links and data

• The hierarchy browser tree component does not permit links in images in node configurations.
• The identifier field can be any value, but using long strings or large data types could cause performance problems. We recommended using a data type's primary key, if available.

Using the nodeConfigs parameter

• The variable fv!nodeValue is only available when the node is used in either the nodeConfigs or nextColumnValues parameters of the browser.
• A hierarchy browser tree node can only be displayed if passed to the nodeConfigs parameter of the hierarchy browser tree.

Examples

For an example of how to configure a hierarchy browser tree node, see the example in the Tree Browser Component page.
