/**
* @module DateDropdown
* DateDropdown components are used to display a dropdown of months and years to handle date selection. Future dates are disabled (current month and year are selectable).
* The component returns an object with selected date info, example: { dateType: 'start', monthIdx: 0, monthName: 'January', year: 2022 }
*
* @example
* ```js
* <DateDropdown @handleSubmit={{this.actionFromParent}} @name="startTime" @submitText="Save" @handleCancel={{this.onCancel}}/>
* ```
* @param {function} handleSubmit - callback function from parent that the date picker triggers on submit
* @param {function} [handleCancel] - optional callback for cancel action, if exists then buttons appear modal style with a light gray background
* @param {string} [dateType] - optional argument to give the selected month/year a type
* @param {string} [submitText] - optional argument to change submit button text
* @param {function} [validateDate] - parent function to validate date selection, receives date object and returns an error message that's passed to the inline alert
