Using ng-class rather than ng-if for icons

            <i ng-if="category == 'text'" class="fa fa-font fa-fw contentIcon"></i>
            <i ng-if="category == 'textarea'" class="fa fa-text-height fa-fw contentIcon"></i>
            <i ng-if="category == 'dropdown'" class="fa fa-list-ul fa-fw contentIcon"></i>
            <i ng-if="category == 'checkbox'" class="fa fa-check-square-o fa-fw contentIcon"></i>
            <i ng-if="category == 'radio'" class="fa fa-dot-circle-o fa-fw contentIcon"></i>
            <i ng-if="category == 'description'" class="fa fa-align-left fa-fw contentIcon"></i>

You better use ng-class to save DOM:

<i ng-class="{'fa-font': category == 'text', 'fa-text': category == 'textarea', 'fa-list-ul': category == 'dropdown'}" class="fa fa-fw contentIcon"></i>

Great suggestion! There is definitely room for refactoring. Will work on this
