Custom JSP taglib for UI development. This taglib is similar to our Custom combo box and lets you create a customized combo box. But here the list of options will be requested via Ajax call from your server side application. For example:
 

Tag assumes that your server side code (described in the attribute url) will return XML data with the available options. E.g. your jsp file content.jsp can looks so:
 

and you will get some like this

Please, select

You can use any server-side application that returns a valid xml for the content (JSP, servlet or even PHP, ASP.NET etc.). In your XML file you can use any node name for the root (ajaxcombo in our example) and options (option in our example). Each option (node) in your XML response defines an option for your combo box. You can provide the following attributes for nodes in your XML response:

value - describes a value for this option
image - describes an image for this option
width - describes a width for your image
height - describes a height for your image
title - describes a title (tooltip) for this option

Note: if you are using JSP for the XML response make sure your XML code starts with the first line.

In order to use this tag you have to describe an external JavaScript file cjajax.js on your page. And of course you have to use this tag inside of HTML form (or form taglib from Coldtags suite).
