The CONDITION element represents the condition under which an ACTION_SET, ACTION_CONTROL, LIST, or a CLUSTER is displayed. If a condition evaluates to true, then the parent element will be displayed; if the condition evaluates to false, then the parent element is not displayed with the following exception: an ACTION_SET or ACTION_CONTROL element will display disabled links if the condition evaluates to false and the HIDE_CONDITIONAL_LINKS attribute on the PAGE element or in the curam_config.xml file has been set to false. Conditional ACTION_SETS and ACTION_CONTROLS are mutually exclusive from one another and therefore the CONDITION element should be set for either one (depending on the requirements) but not both.
Finally, if the condition equates to false for those conditional action sets or action controls which appear as drop down menu items, then a single disabled menu item titled, 'No Contents' is displayed (upon selecting the drop down menu icon).
