GeoJSON Information

Hi, everyone.
I´m new in Cesium. So my trouble might be basic.
I´m trying to find out the correct way to show the information GeoJSON has.
The example of Sandcastle shows information of GeoJSON in a incredible way. Captura1 Captura2

But in my app, the information does´t look fine.
Can someone tell me the correct way of the information in the geoJSON to show in a similar way or how can I decide the information I wanna show?
Thanks for your help!
