Hi, I'm a novice when it comes to SharePoint and jQuery but have found several posts online regarding using jQuery on a SharePoint site increase functionality. All I'm trying to do is use a Web Part to create an "expand/collapse all" button so I can easily clean up a Task List and hide subtasks. I'm running into trouble when it comes to where to store the jquery file and how to enable it on my Master Page so that the Web part works. Any advice?
