jquery ui datepicker modification.

Question

i would like to display some information about the datepicker when input field is clicked. something similar to this

i want to show information about the datepicker where "from" and "to" fields in this image are placed.

i guess the logic applied here is that when clicking the input, it shows a div, inside which is their calendar. but i dont have good grasp of javascript to understand the code. can i get some code examples how this was done with some explanations. my requirements of datepicker was met from:
