Button Input Option

[rtjohnson12]

Is there an easy way to mimic shiny::dateRangeInput's UI? I'd like to make daterangepicker look like this (with the entire container being a single button).

It looks like there's a way to make the original daterangepicker appear as a button (here http://www.daterangepicker.com/#ex4), but I'm having trouble getting it to work. Any help or pointers would be greatly appreciated!
