Using Vis 2 only the following widgets are available:

According to the description more widget functionality should be available.

Versions:

• Adapter version: 1.5.0
• JS-Controller version: 6.0.11

A more detailled review (done by oweitman - THANKS) showed that currently only 5 widgest are implemented. Those are visible at vis-2.

Reading the README.md in more detail shows that one should click onto the description of the widgest. This shows that only some widgets are widgest provided by spotify adapter. Other examples use jqui widgets, i.e. tplJquiSelectList.

So everything is ok - except that the documentation could more clearly state, that not all widgets shown are delivered by spotify-premium adapter.
