UWP - уменьшите всплывающую часть SplitButton

0 голосов
/ 05 мая 2020

У меня есть SplitButton в UWP, который выглядит так: own SplitButton

Примечательно, что между моим значком и стрелкой всплывающего окна есть огромный разрыв, поскольку всплывающая часть SplitButton слишком широка для меня.

Я хочу добиться чего-то вроде этого (из OneNote), где всплывающая часть намного меньше: enter image description here

Как это возможно с UWP SplitButton?
