Customizing Digital Screens
Customizing Digital Screens
Nosto's UGC Digital Screens features a full templating framework, as well as custom HTML, JavaScript, and CSS capabilities for developers to add their layouts, transition, data management and so much more.
Without writing any code, you can easily change Digital Screen's look and feel by adjusting its display options. The available options vary according to the Digital Screen type you selected.
Ideally, you should change any Event Screen settings via the Admin Portal. However, you might feel that it's extremely useful to preview changes by modifying URL parameters. The following snapshot illustrates a Wall Screen that is configured to show 2 columns, but uses the ?columns=4 GET parameter to show 4 columns on-the-fly. You can see the Configurable Options section for more information.
You can customize stylesheet by updating Custom CSS tab
The following diagrams illustrate the default tile HTML structure of current 2 Event Screen types.

We've exposed our Event Screen JavaScript instance for you to hack. You can customize it by providing window.StacklaEventscreens.options
config object before the Event Screen instantiates. You can also subscribe eventscreen:ready
event which is triggered immediately after Event Screen has been instantiated.
For more detail, please check the Event Screen JavaScript API documentation.
No matter which Event Screen type you are using, it is always composed by many tiles. You can have your customized tile template by enabling the Custom Template. To write your own template, you must learn to use Mustache, a very famous template engine. Check Tile Data section to see what are the fields you can use in your template.
You can use all fields from data service in Custom Template. Besides, we also added several useful data fields that you might need as well.
Our developers add debugging logs for every methods that event screen executes. By adding ?debug=1 as an extra URL parameter, you will see these logs in Developer Console. It's sometimes easier for you, as a developer, to investigate your Custom JavaScript issues.
