Add a functionnality to a existing mobile App

Hi, I've started to make a App for my company. It's based on a CodeCanyon package than i customize. Everythinig goes fine till now, but i need a specific functionnality. The package is based on a Wordpress backend, it contains everything i need to manage registered/unregistered WP users, except for one think : i need to show/hide elements in the app Menu for registered/unregistered users. I'm totaly new to AngularJS, and have no time to chieve this, so, if someone could help. It's no big deal i guess. Services for Login and authorisation is already implanted in the app, but need to be enhanced. Something like that : [login to view URL] I need a directive than i wan sue in the HTML to show hide elements by registration conditions : <div data-show-when-connected> Hello {{userName}} ! </div> <div data-hide-when-connected> </div
