Usage considerations

Drillable and selectable nodes

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.
  • 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.
