I spent few hours looking for a solution to fill an element with 100% height and no solution for this. So I wrote this directive that could help.
<ion-content>
<div fill-content>
</ion-content>
.directive('fillContent', function ($ionicScrollDelegate) {
return {
link: function ($scope, element, attrs)
{
element.ready(function () {
element[0].style.height = $ionicScrollDelegate.getScrollView().__clientHeight + 'px';
});
}
};});
