I have something like this, and the <option> tag needs to be selected
when id matches the value of the parameter called location-id.

<p><label for="location-id">Location: </label>
<select id="location-id" name="location-id">
<option value="">Choose a location</option>      	      		
   <!-- tmpl_loop rows -->
      <!-- tmpl_loop cols -->
	<option value="<!-- tmpl_var id -->">
              <!-- tmpl_var name --></option>
      <!-- /tmpl_loop -->
   <!-- /tmpl_loop -->	   	
</select></p>

So I followed Igor's advice (thank you!) and changed the <option> tag
above to this:

<option <!-- tmpl_var selected --> value="<!-- tmpl_var id -->">
              <!-- tmpl_var name --></option>

Supported by this code:

(rows (loop for locationl in locations
      collect (list :cols
	    (loop for location in locationl
	       if (and (required-exist-p location-id)
       		       (equal (parse-integer location-id
				:junk-allowed t)
		              (id location)))
	       collect (list :id (id location)
			     :name (name location)
			     :selected "selected")
	       else collect (list :id (id location)
				  :name (name location)))))

It's working now. Do let me know if there are better ways to achieve this.


Vamsee.
