ng-if
Description
ng-if removes or recreates an element in the DOM based on an expression.
ng-if is different from ng-show and ng-hide. ng-if removes and recreates DOM nodes, rather than just showing and hiding them via CSS.
Example
The following code shows how to ng-if.
<!doctype html>
<html ng-app="myApp">
<head>
<link rel="stylesheet" href="http://cdn.jsdelivr.net/foundation/4.3.2/css/foundation.min.css">
