   I've set up a custom hierarchal taxonomy called Make & Model, with the make as parent categories, and models as child categories of the makes. For example:

   BMW
   - 318i
   - Isseta
   Daewoo
   - Espero
   - Laganza

   What I'd like to do is to display the parent category on it's own (and then the child category/ies) on their own within the individual post. For example:

   Make: BMW
   Model: Isseta

   Is that at all possible?

   Thanks

   No one has attempted something like this before, or knows how it could be done? Any help will be appreciated.

   This is how I'm doing it:

   1. The taxonomy slugs:

   parent taxonomy slug: bmw
   child taxonomy slug: bmw-isseta

   2. The set up:

   <?php if(get_the_terms($post->ID,'model')){
   $makemodel = wp_get_object_terms($post->ID, 'model', array('orderby' => 'slug')); } ?>

   3. Outputting the make:

   <?php if(!empty($makemodel) && get_term_link($makemodel[0])){ ?>
   <a href="<?php echo get_term_link($makemodel[0]); ?>"><?php echo $makemodel[0]->name; ?></a>
   <?php } ?>

   4. Outputting the model:

   <?php if(!empty($makemodel) && get_term_link($makemodel[1])){ ?>
   <a href="<?php echo get_term_link($makemodel[1]); ?>"><?php echo $makemodel[1]->name; ?></a>
   <?php } ?>

   Thanks aljuk, that looks like a nice simple way of doing it.

   I ended up using a different method which checks for if the the category has a parent or not:

   For make:
   <?php $make =""; $i = 1; foreach((get_the_terms( $post->ID, 'make' )) as $makecat) {if ($makecat->parent == 0) {$make .= $makecat->name; if($i == 1) break;}} echo $make; ?>

   For model:
   <?php $model =""; $i = 1; foreach((get_the_terms( $post->ID, 'make' )) as $modelcat) {if ($modelcat->parent |= 0) {$model .= $modelcat->name; if($i == 1) break;}} echo $model ?>
