Multi column combo box taglib

Custom JSP taglib for UI development. This taglib lets you create a multi column combo box. For example:

<%@ taglib uri="taglib.tld" prefix="m" %>

<m:MultiColumnComboBox name="m" listBackground="yellow">

<m:option value="1" onMouseOver="this.style.background='gray'" onMouseOut="this.style.background='yellow'">One</m:option>

<m:option value="2" onMouseOver="this.style.background='gray'" onMouseOut="this.style.background='yellow'">Two</m:option>

<m:option value="3" onMouseOver="this.style.background='gray'" onMouseOut="this.style.background='yellow'">Three</m:option>

<m:option value="4" onMouseOver="this.style.background='gray'" onMouseOut="this.style.background='yellow'">Four</m:option>

</m:MultiColumnComboBox>

You may obtain options through some array (collection, iterator etc.) and use this object for building your control:

<%
   java.util.Vector v=new java.util.Vector();
   v.addElement("Java");
   ...
%>

<m:MultiColumnComboBox name="m" listBackground="yellow" columns="3" source="<%=v%>" />

In this example (our collection contains Strings) tag iterates over elements and creates the control. You can pass a collection of beans also and describe how to get the value and text for options. Attribute option specifies what getXXX method is called on each item in your source for getting options. Attribute value does the same for values. E.g. option="name" means that that getName() call is used for getting options etc.
