Help creating time item from UI widget

  1. What ever binding it’s linked to now. If it’s not linked to a Thing now, then you don’t link it to anything.

1 A card is usually a stand alone self contained widget that you’ll see on a Page. A cell you will usually see as part of a card or as a pop-up (e.g. in the developer sideboard when you hover over an Item the widget that pops up is a cell). I’ve never actually done much with cells yet.
