Returns
Section titled “Returns”boolean
isItemActive()
Section titled “isItemActive()”isItemActive(
i):boolean
Is the item-center merge zone for child[i] currently active?
Parameters
Section titled “Parameters”number
Returns
Section titled “Returns”boolean
isTrailingGapActive()
Section titled “isTrailingGapActive()”isTrailingGapActive():
boolean
Is the trailing gap (after the last child) currently active?

onDragMoved()
Section titled “onDragMoved()”onDragMoved(
event):void
Forward pointer position to the service on every drag-move tick.
Parameters
Section titled “Parameters”CdkDragMove
Returns
Section titled “Returns”void
onDragStarted()
Section titled “onDragStarted()”onDragStarted():
void
Returns
Section titled “Returns”void
onDrop()
Section titled “onDrop()”onDrop(
event):void
CDK fires this when an item is dropped into THIS branch’s drop list.
Resolves the drop position by running findDeepestBranchZone fresh at the drop coordinates — the same geometry used for hover highlighting — then emits nodeDrop with the fully resolved position. The root FilterTreeComponent applies the mutation.
Parameters
