In addition, the following attributes are also supported. These may be set on either this element itself, or on the calling element which invokes this element. If set on both, the caller's setting takes priority:

attribute description
comparison Indicates that the dialog is for secondary series (comparisons).
cq-maintain-case When set to truthy value, maintains case of entered symbol. Otherwise, symbol is capitalized before processing.

Emitters

A custom event will be emitted by the component whenever the search input is changed. See CIQ.UI.BaseComponent#emitCustomEvent for details on how to listen for this event. The details of the event contain the following:

property value
emitter this component
cause "useraction"
effect "search"
action "input"

emitCustomEvent(params)

Emits a custom event from the webcomponent. The event type of the emitted event is determined by the particular user action taken. Up to two events are emitted when this function is executed. The first is an event with the type of action performed, if there is one. For example, events which are spawned without user action will not emit this first event. The second event will have a type derived from the component name. For example, the cq-study-legend component will emit a "StudyLegend" type event. The payload of the event will contain a detail section specifying the component which emitted the event as well as the effect - which more clearly defines the type of action causing the emittance. The detail section may also include custom fields further categorizing the event and providing additional information. These details are documented within the web component's documentation.

Parameters:
Name Type Description

focusNextItem(items [, reverse] [, loop])

Focuses the next item in the tab order.

Locates the first element in items that has a cq-focused attribute. If an element is found, the attribute is removed from all elements in items, and cq-focused is applied to the element that follows (in the tab order) the element that was found.

Unless loop is set to true, then focus is applied to first element.
