[Support request] Drop Down Menu

[kunal]

Hi David and Tom,

I have some secondary navigation categories. What I would like to do have a box (almost like a Table of Contents box), that goes under the title of the category.

The link that I provided is an illustration of what I would like to do

GeneratePress 2.2.2

Hi there,

Should be pretty easy.

1. Create a new Hook Element: https://docs.generatepress.com/article/hooks-element-overview/
2. Set the hook to after_archive_description
3. Check the Execute PHP checkbox.
4. Add this as your content:

<?php
	$current_cat = get_queried_object();
	$args = array( 'child_of' => $current_cat->term_id );
	$categories = get_categories( $args );
	
	if ( ! empty( $categories ) ) {
		echo '<p>Find out more:</p>';
		echo '<ul>';
			foreach ( $categories as $category ) {
				echo '<li><a href="' . get_category_link( $category->term_id ) . '" title="' . sprintf( __( "View all posts in %s" ), $category->name ) . '" ' . '>' . $category->name.'</a></li>';
			}
		echo '</ul>';
	}
?>

5. In the Display Rules, set it to “Post Category Archive”.

Hi Tom, thanks for the reply… .but… still no luck! I put the code as above, and still no output. Only the environmental category has a child category, so only this category archive page should have an output, but there is no output of the children categories?
thanks Tom!

Ah, you’re using a Page Hero instead of the standard archive description.

In that case, you need to create a shortcode:

add_shortcode( 'subcat_links', function() {
    ob_start();
    
    $current_cat = get_queried_object();
    $args = array( 'child_of' => $current_cat->term_id );
    $categories = get_categories( $args );
	
    if ( ! empty( $categories ) ) {
        echo '<p>Find out more:</p>';
        echo '<ul>';
        foreach ( $categories as $category ) {
            echo '<li><a href="' . get_category_link( $category->term_id ) . '" title="' . sprintf( __( "View all posts in %s" ), $category->name ) . '" ' . '>' . $category->name.'</a></li>';
        }
        echo '</ul>';
    }

    return ob_get_clean();
} );

Then add the shortcode to the Header Element in the Elements area:

[subcat_links]
