The callback argument sets the callback that will be invoked when the event is dispatched.
The options argument sets listener-specific options. For compatibility this can be a boolean, in which case the method behaves exactly as if the value was specified as options's capture.
When set to true, options's capture prevents callback from being invoked when the event's eventPhase attribute value is BUBBLING_PHASE. When false (or not present), callback will not be invoked when event's eventPhase attribute value is CAPTURING_PHASE. Either way, callback will be invoked if event's eventPhase attribute value is AT_TARGET.
When set to true, options's passive indicates that the callback will not cancel the event by invoking preventDefault(). This is used to enable performance optimizations described in ยง 2.8 Observing event listeners.
When set to true, options's once indicates that the callback will only be invoked once after which the event listener will be removed.
If an AbortSignal is passed for options's signal, then the event listener will be removed when signal is aborted.
The event listener is appended to target's event listener list and is not appended if it has the same type, callback, and capture.
Optionaloptions: boolean | AddEventListenerOptionsCallback method called when context is resolved.
Reference to the created Context Consumer Controller instance
Dispatches a synthetic event event to target and returns true if either event's cancelable attribute value is false or its preventDefault() method was not invoked, and false otherwise.
A Promise with the reference to the Context Api Instance
An Observable to observe from.
Optionalcallback: ObserverCallback<SpecificT>Callback method called when data is changed.
OptionalcontrollerAlias: null | UmbControllerAliasDefine an explicit controller alias. If not defined then one will be generated based on the callback function. If null is parsed no controller alias will be given.
Reference to the created Observer Controller instance.
The API instance to be exposed.
Reference to the created Context Provider Controller instance
Removes the event listener in target's event listener list with the same type, callback, and options.

UmbSorterController
Implements
Description
This controller can make user able to sort items.
Example
This example shows how to setup a sorter controller with no special needs. Assuming your declaring this on a Umbraco Element(UmbControllerHostElement):
