Each group ends with a line separator. If each item in your menu has its own group you will achieve the desired graphical output. It will work only if your different groups have different android:id
. Also, in menu.xml
remember to mention android:checkable="true"
for single item and android:checkableBehavior="single"
for a group of items.
