It seems not WYSIWYG when I using a simple menu bar

Hi when I use a simple menu bar, the icon is on top of the menu text, but in runtime the icon always shows on left of the menu text. how can I fix it? I’m using Mendix Studio Version 8.10

Seems that you added the menubar under the scroll container

Add a bottom region in your Scroll container and add the navigation in it.
