The following are examples of supported markup. On their own, these will not provide a datepicker widget; you will need to instantiate the datepicker on the markup.
The simplest case: focusing the input (clicking or tabbing into it) will show the picker.
date class to an
input-group bootstrap component will allow the
input-group-addon elements to trigger the picker.
input-daterange construct with multiple child inputs will instantiate one picker per input and link them together to allow selecting ranges.
