maximumDisplayedItems
Number of maximum suggested items displayed in the dropdown.
If more items match the query than specified in this threshold, only the first n items are displayed.
Important: Since the rendering of the dropdown-items is by far the most expensive operation in the combobox's rendering workflow, this value has a direct impact on the overall performance of the component!
In most cases, due to the expensive rendering, a smaller number of items should be favored over larger lists. If a larger amount is explicitly needed it may be necessary to adjust inputDebounceMillis and renderDebounceMillis too, as rendering should occur as few times as possible in this case.
