Module fields 

The form controls (a themed surface expands each into its recipe parts): Input/Textarea, Select (the combobox, its popup a LAYER), DatePicker and DateRangePicker (one calendar layer), TimePicker (a list layer), NumberField (steppers), ChipInput (chips + suggestions layer), FileUpload (drop zone + files), Checkbox/Switch, Radio, Slider and the Form that collects them. A field’s failed checks (after a refused submit) show under it as <field id>.error and put its parts in the invalid state.
