To use the parallax scroll view you need to have to containers inside of the <parallax-view></parallax-view> tag. one container needs the head attribute and the other the body. In the above example they are both StackLayouts

You can specify the head containers height with <parallax-view head-height="<VALUE>">

If you have controls you want to fade out with the scroll of the head container their id's can be passed as array of strings like so: <parallax-view [controls-to-fade]="['control1','control2']">.

Both the head-height and controls-to-fade are not required. If no head-height value is set then it defaults to 300.

Special thanks to Nathan Walker for setting up the Angular 2 Plugin seed that I used to help get this plugin up and running. More info can be found about it here: https://github.com/NathanWalker/nativescript-ng2-plugin-seed
