filtering combobox
<p>I have four dropdown lists.The three of which is filtered on the session value but the fourth one needs to be filtered on the values of the three dropdowns.I have four different functions for loading the dropdowns.The functions query to the database and creates the dropdown.
The functions are given below.How can I do that?Can anybody help.</p>

<pre><code>ComboLoader-&gt;getUserTypeForDocUpload('utTriggerDept','ut','required nep',true,$_SESSION['offTyp'],'userSubtypeIDTriggerDept','छान्नुहोस','');
</code></pre>

<p>The first parameter triggers the second dropdown function.The second parameter is the id of the dropdown,the third one is the class,the fourth is for editing option,the fifth is for filtering the second dropdown used in querying,the others are for triggering the third function and default option.The other two dropdowns are the same which uses session value for filtering but for the fourth dropdown the values of the previous dropdowns sre required for filtering.  </p>
