How do I populate the other dropdown value based on the first dropdown

[yogi564]

Hi all,
Can somebody help me out. I wondering if there is a way to populate other dropdown box based on the first dropdown selection. The coding is given below

<select name=&quot;pan_cementum_cd&quot;>
<cfloop query=&quot;PC&quot;>
<option value=&quot;<cfoutput>#PC.Code#</cfoutput>&quot;><cfoutput>#PC.Code#|#PC.Description#</cfoutput></option></cfloop>
</select>
*

Pan Type <select name=&quot;pan_type_cd&quot;>
<cfloop query=&quot;PT&quot;>
<option value=&quot;<cfoutput>#PT.Code#</cfoutput>&quot;><cfoutput>#PT.Code#|#PT.Description#</cfoutput></option>
</cfloop>
</select>


Pan Continuity
<select name=&quot;pan_continuity_cd&quot;>
<cfloop query=&quot;pcon&quot;>
<option value=&quot;<cfoutput>#pcon.Code#</cfoutput>&quot;><cfoutput>#pcon.Code#|#pcon.Description#</cfoutput></option>
</cfloop>
</select>






Pan Structure
<select name=&quot;pan_structure_cd&quot;>
<cfloop query=&quot;PS&quot;>
<option value=&quot;<cfoutput>#PS.Code#</cfoutput>&quot;><cfoutput>#PS.Code#|#PS.Description#</cfoutput></option>
</cfloop>
</select>

From this &quot;pan_cementum_cd&quot; dropdown field I need to control what should appear in the other 3 dropdown values. Is there a way to do it, if so please help me out. Thank's

The answer is JavaScript, and here is a link to one of my favorite sites for JavaScript. Scroll down and look for Dropdown Box Population. I haven't used this particular one, but there are a few others in this same list that do similar things.

I try to use this coding and it doesn't help much at all. The reason for this is that the <cfoutput> tag doesn't click properly with the array define at the top. I need something that works with the <cfoutput> tag's. Thank's.
