Where does the number zero shown in the picture in the Employee center portal come from when the menu does not fit on the screen and how can I get rid of it? Is it possible that a hamburger menu would appear instead of a number?
Looks like it's badge count on the My Requests menu item. This is OOTB behaviour and to my knowledge not something which is a simpole config job to turn on/off. Getting rid of it would require you to alter the css for tag sp-navbar-badge-count in the the Header Menu. You will see it referenced in multiple places in the Body HTML template of the header widget....
You would need to play around with using the css xs, sm, md, and l tags to get this to appear not appear depending on the size of the device. This would be customization that you would need to own so be careful.
