Hi, I'm trying to implement the most elegant calendar tool in several forms on my web site, that will allow the user to select a date quickly and easily. I've seen controls that appear to the right of text fields, and when you click on them (they appear to be little compressed calendar images) they expand into a larger calendar that allow you to selected year, month and day. Once you select the exact date, it collapses back into its original form and the date is populating the text field. Any ideas for how I could get this? 3rd party components? I'm using PHP. Thanks, plywood

There's many for jQuery as well. See here

HTML5 has added native date picker control. (Although not supported yet by most browsers)
