I’ll look into this and see.
I was looking into doing something similar and added the get_categories attribute ‘parent’ to the plugin and it seems to have worked.
public function shortcode( $atts ){
/* Extract shortcode attributes, set defaults */
extract( shortcode_atts( array(
'taxonomy' => 'category',
'title' => 'Categories',
'title_container' => 'h3',
'columns' => '3',
'orderby' => 'name',
'order' => 'ASC',
'show_count' => '0',
'exclude' => '',
'parent' => '',
), $atts )
);
/* Build an array of arguments for the get_terms parameters */
$args = array(
'parent' => $parent,
'orderby' => $orderby,
'order' => $order,
'show_count' => $show_count,
'exclude' => $exclude
);
Once added, I was able to use [mctl taxonomy=’category’ parent=’3′] to display only children of category 3.
get_categories calls get_terms anyways and adding the parent attribute is the solution I came to as well, I just haven’t had a chance to update the plugin yet. Expect a new version sometime this week.
The new version is now live. It includes the ability to limit based on parent as well as a couple other features, too.
