This tutorial applies for Classic ASP, JSP, and PHP but not for ASP.NET. ASP.NET developers should see the Writing a Basic Combo Page (ASP.NET) tutorial instead.
Setting up Your Files
Create an empty ASP/JSP/ or PHP page.
From the directory where you installed Nitobi ComboBox, copy the entire contents of the bin directory including .js, .css and image files to the same location where your project resides.
Include the JS file and set up the basic elements for Combo
Make sure you include the xml namespace statement in the <html> tag. Next we include the JavaScript and CSS files, and make sure that the necessary initialization methods are being called in the onLoad <body> event.
Note the onload attribute of the body calls our special initialize() function with the necessary calls.
