 * hacking around some wordpress default theme.
 * what i am trying to do is create a custom page template that when applied shows
   posts in that category using post meta. this is working well.
 * however, i’d also like the menu to display only the parent category and children
   of that the category.
 * i’m trying to replace `child_of=3` to `child_of=$categori_id`
 * here is the code
 *     ```
       <div id="sidebar" class="internet_bar">
       			<ul>	<?php
       				if (is_page() ) {
       			$categorize = get_post_meta($posts[0]->ID, 'category', true);
       			}
       		if ($categorize) {
       			$categori = get_the_category();
       			$categori_id = get_cat_ID($categorize);
   
       				echo "<li>" . $categorize ."</li>";
       				$categlories=  get_categories('child_of=3');
       		  foreach ($categlories as $categlory) {
       		  	$option = '<li>'.$categlory->category_nicename.'</li>';
   
       			echo $option;
       		  }
   
       		}
       		?> 
   
       			</ul>
       			</div>
       ```

 * online only is parent, other two categories are children

 * Not quite sure, but I think this is what you want:
 * `$categlories= get_categories("child_of=$categori_id");`
