The list of currently available themes is:
The install package of jqSuite for PHP comes with just the default Redmond theme. It is available in the [themes] folder of the install package. You can download any additional themes directly from jQuery UI's ThemeRoller site available here:
http://jqueryui.com/themeroller/
You can also create a new theme (either from scratch or based on another theme).
Just add reference to the ThemeRoller theme in your PHP file.
Example:
<head> <link rel="stylesheet" type="text/css" href="themes/redmond/jquery-ui.custom.css" /> ... </head>
If you wish to use one of the other 25 themes ThemeRoller offers or your own theme, just replace the Redmond css file with the CSS file of the respective theme.
