    selected: ["2017-10-16T00:00:00-03:00", "2017-10-27T00:00:00-03:00", "2017-11-05T00:00:00-03:00"],
    channels: {0: ["2017-10-16T00:00:00-03:00", "2017-10-27T00:00:00-03:00", "2017-11-05T00:00:00-03:00"]} // if channels are available
}

DayComponent

A component that will render on each day, it receives several props where the most importants label and isSelected.

• Label: String; Represents the day character.
• isSelected: Booleam; True if the day is included in the selected array.
• isCurrentChannelSelected: Booleam; True if the day is included in the selected array for the current channel.
• isToday: Booleam; True if the value match today;s date.
• isInThePast: Boolem; True if the value is before than today.

Some other properties are expose like selected which is the selection array, we expose it cause we need that rule to manage inside business cases.

If you require that past days not be selected, you need to stop the propagation of the click event yourself.

Common use example:

const PositionDay = props => {
  const onClick = (e) => {
    if (props.isInthePast) {
      e.stopPropagation()
    }
  }
  return (
    <div onClick={onClick}
      className={getStyle(props)}
      style={getInline(props)}>
      {props.label}
    </div>)
}

const getStyle = function ({date, isSelected}) {
  return `${isSelected ? 'o_selected-day' : ''} ${date.type}-day`
}

const getInline = ({isToday, isInThePast}) => ({
  cursor: isInThePast ? 'not-allowed' : 'inherit',
  background: isToday
  ? 'rgba(141, 224, 229, 0.5)'
  : isInThePast ? '#e4e4e4' : 'inherit',
  color: isInThePast ? '#555555' : 'inherit',
})

As you can see, we leave the default implementation as open as possible, this way we can support all the use cases we have into our apps.

Styles

We expose a few css clases that you can edit, otherwise, you can use our ugly css default.

• o_day_picker: the calendar container
• i_day-picker-header: weeks headers
• i_day-picker-body: calendar body
• e_day-picker-buttons: prev and next month
• i_day-picker-row: weeks row
• i_day-picker-reset: reset button
• i_day-picker-add-channel: add channel button
• o_selected-current-channel-day: date selected for current channel
