Angular datepicker and date range picker

The options attribute is a type of IAngularMyDpOptions. It has the following optional properties.

defaultMonth attribute

Visible month/year when calendar is opened:

• If date is already selected => calendar opens to the month and the year of the selected date
  • In date range mode => calendar opens to the month and the year of the selected begin date
  • If an overrideSelection property is set to true in the IMyDefaultMonth the calendar opens to the month and the year specified in the the defaultMonth attribute even the date is selected.
• If the defaultMonth is set => calendar opens to the month and the year specified in the the defaultMonth attribute
• If none of above => calendar opens to the month and the year of current date

Value of the defaultMonth attribute can be:

• IMyDefaultMonth object. The value of defMonth property can be a string which contain year number and month number separated by delimiter. The delimiter can be any special character. For example: 08-2019 or 08/2019.
• a string which contain year number and month number separated by delimiter. The delimiter can be any special character. For example: 08-2019 or 08/2019.
