calendar dropdown list

[MrEmz]

Greetings! How can i make a calendar dropdown list wherein i click on dropdown and a specific date will appear in the list. For example, i clicked now on the dropdown and the weekends list will appear including friday like 10/12-14/12, 10/19-21/12, 10/26-28/12 and so on. The list is a weekender. If the user chooses 10/12-14/12, then all items on that date will appear. Is this complicated? Need help!

What im planning to do is to make a dropdown list with a size of 26 wherein it will get the weekends for 6 months. As i calculated, 6 months in the calendar is 26 weekends. And then, if the user chooses one item in the list, for example 10/26/12-10/28/12, the calendar checkin will get the 10/26/12 and checkout will get 10/28/12 and will return the inventories available for that period. I'll be using the check availability calendar here. Help! Thanks in advance!
