(default: true) Node is drillable isDrillable Boolean If true, clicking the node will save the columns browser's navigation path, revealing another column to the user. If false, clicking the node will not reveal another column. It may still save the navigation path if the node is selectable. On hover, a drillable node will have a unique display.

Usage considerations Drillable and selectable nodes You can see some of these terms and parameters (isDrillable and isSelectable) labeled in the following screenshot. Using the nodeConfigs and identifier parameters A columns browser node can only be displayed if passed to the nodeConfigs parameter of the columns browser. The variable fv!nodeValue is only available when the columns browser node is used in either the nodeConfigs or nextColumnValues parameters of the columns browser. 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 links with the columns browser The columns browser component does not support dynamic links nor submit links node configurations. The columns browser component does not permit links in images in node configurations. Examples For an example of how to configure a columns browser node, see the example in the Columns Browser.
