• Picker(...) takes 3 parameters: label, selection (binding to the thing where selected value is saved), and the views (you provide a bunch of views to choose from
  • Add.tag(...) to the view that's clicked because this line will then update second argument to be what value is inside tag
  • Looks much better whenPicker is put insideForm
    • Form needs to be insideNavigationView to make it clickable
