What is displayView()?

displayView()... wait for it... displays your views! Pretty simple, huh?

displayView()
Argument Type Required? Description
viewname string Required The name of the view you want to call.

In multiple controllers or assigned controlleres:
controllerName + actionDelimiter + actionName
e.g. home.welcome

You can also use a / instead of your actionDelimiter. home/welcome also works in LightFront.

Another added feature is the ability to go more than two levels deep. Try this for an example.
content any Optional Any data you want to pass into the view. You can pass content to the view just by using the variables or the request scope.
