Description Usage Arguments Value Examples

DatePickerRange is a tailor made component designed for selecting timespan across multiple days off of a calendar. The DatePicker integrates well with the Python datetime module with the startDate and endDate being returned in a string format suitable for creating datetime objects. This component is based off of Airbnb's react-dates react component which can be found here: https://github.com/airbnb/react-dates

`end_date`	Character. Specifies the ending date for the component. Accepts datetime.datetime objects or strings in the format 'YYYY-MM-DD'
`min_date_allowed`	Character. Specifies the lowest selectable date for the component. Accepts datetime.datetime objects or strings in the format 'YYYY-MM-DD'
`max_date_allowed`	Character. Specifies the highest selectable date for the component. Accepts datetime.datetime objects or strings in the format 'YYYY-MM-DD'

`is_RTL`	Logical. Determines whether the calendar and days operate from left to right or from right to left
`reopen_calendar_on_clear`	Logical. If True, the calendar will automatically open when cleared
`number_of_months_shown`	Numeric. Number of calendar months that are shown when calendar is opened
`with_portal`	Logical. If True, calendar will open in a screen overlay portal, not supported on vertical calendar
`with_full_screen_portal`	Logical. If True, calendar will open in a full screen overlay portal, will take precedent over 'withPortal' if both are set to true, not supported on vertical calendar
`first_day_of_week`	A value equal to: 0, 1, 2, 3, 4, 5, 6. Specifies what day is the first day of the week, values must be from [0, ..., 6] with 0 denoting Sunday and 6 denoting Saturday

`className`	Character. Appends a CSS class to the wrapper div component.
`updatemode`	A value equal to: 'singledate', 'bothdates'. Determines when the component should update its value.

`loading_state`	Lists containing elements 'is_loading', 'prop_name', 'component_name'. those elements have the following types: - is_loading (logical; optional): determines if the component is loading or not - prop_name (character; optional): holds which property is loading - component_name (character; optional): holds the name of the component that is loading. Object that holds the loading state object coming from dash-renderer
`persistence`	Logical \| character \| numeric. Used to allow user interactions in this component to be persisted when the component - or the page - is refreshed. If 'persisted' is truthy and hasn't changed from its previous value, any 'persisted_props' that the user has changed while using the app will keep those changes, as long as the new prop value also matches what was given originally. Used in conjunction with 'persistence_type' and 'persisted_props'.
