<div class="markdown level1 remarks"><p>The default setting for this property is &quot;InputKeyAction.OpenDropdown&quot;,which opens the listbox and filters options as the user types.This allows users to see matching options before making a selection.Alternatively, you can set this to &quot;InputKeyAction.ChangeSelectionOnly&quot; to immediately change the selection to match the typed characters while keeping the listbox closed. This is useful for quick selection in known-value scenarios.</p>
