How to implement my own date selection box using Calendar

[morib]

Hi, I need a special date selection box that contains a free text entry field and a calendar that is shown on click of a small calendar icon.  I tried the option of hiding the calendar on load of the page and then showing it on click of the calendar icon but the problem is that when the calendar object is shown, the other objects on the page are "pushed down" in order to make place for the calendar object.  What I would like to have is the calendar to show "over" the other objects on the page - just like the datebox does.

Please let me know how to do this.

Thanks!
