Datepicker Inline with Multiple Select

[jshster]

Hey all,
Just leaning on the community for some help. I have a requirement to allow a user to select a start date, and end date and then have the ability to select multiple dates within that date range.

So what I need is effectively the datepicker popup but with an ability to display multiple months in a single display and then allow for the selection of multiple dates.

Effectively I'm looking for this http://keith-wood.name/calendarsPicker.html (click on the Range tab to see what I mean) but in Material form.

Has anyone seen anything like this? It seems like a relatively straight forward concept to perhaps even just create the interface myself but I don't want to reinvent the wheel.

It's being integrated with a MaterialCSS implementation.

Thanks for any help.
