I want to render a navbar that is relatively tall; the default height is 50px. I'm trying to render one about 150px. When I render a split button, the menu drop-down doesn't respect the navbar height. How do I fix this? Also, if anyone has a suggestion on how to get rid of the gap in the middle of the button group, that'd be awesome too!
