Modify angularjs script

I have an angularjs app seen here [login to view URL] and I have 4 things that I need done to the Angularjs app. 1. In the “Filter By Content” select menu at the top, if you have selected an item that name should appear in the select menu instead of “Filter By Content”. 2. After you select a Content Area, the topics should filter to only show topics within that Content Area in the select menu for Topic Category. 3. Also, you should be able to select multiple items in the Topic Category select menu. You should only be able to select 1 content area, but multiple Topics. 4. I need to be able to make the items in the resource column links. In the data file the resources are actual links similar to <a href="[login to view URL]">resource content here</a> This is a simple job that can be complete within an hour or so. Please only bid if you can start and complete this within the next few hours.
