MenuCssClass

MenuCssClass is used to add css to the Menu node. The css allows for replacing menu with an icon and other super-fun and helpful things. cssClass is a StringFunc which can either be a String constant or a Function that returns a String. Thus, you can compute the css based on the current state or you can have a constant. Syntactically you can use either:

 MenuCssClass("foobar") MenuCssClass(() =>
calculateCssForMyMenuItem())
