Orbit is the name of the Foundation slider. Depending on the size and quality of your images, you can set it to cover a small part of a web page , or the whole width 'wall-to-wall'.
Slides can be added by duplicating one of the 'list item containers'. If you add - or remove - slides, you also need to adjust the number of the indication bullets. Or, if you don't want those bullets, you can delete the container .orbit-bullets.
With the upgrade to the 6.6.3 version of Foundation we are now able to create variations of the basic Orbit slider. Two such variations are included, the vertical and the fade options. You can find more options among the transition classes here:
To be able to build those variations, you need to have Site Designer 4.0.3285 or later.
