Sì,puoi utilizzare get_categories () utilizzando l'attributo 'child_of'. Adesempio,tutte le sottocategorie di categoria con ID 17:

 $args = array('child_of' => 17);
$categories = get_categories( $args );
foreach($categories as $category) { 
    echo '<p>Category: <a href="' . get_category_link( $category->term_id ) . '" title="' . sprintf( __( "View all posts in %s" ), $category->name ) . '" ' . '>' . $category->name.'</a> </p> ';
    echo '<p> Description:'. $category->description . '</p>';
    echo '<p> Post Count: '. $category->count . '</p>';  
}

Otterrannotutte le categorie discendenti (adesempiofiglie nipoti).

Se desideri visualizzare solo le categorie che sono discendenti diretti (cioè solobambini),puoi utilizzare l'attributo 'parent'.

 $args = array('parent' => 17);
$categories = get_categories( $args );
foreach($categories as $category) { 
    echo '<p>Category: <a href="' . get_category_link( $category->term_id ) . '" title="' . sprintf( __( "View all posts in %s" ), $category->name ) . '" ' . '>' . $category->name.'</a> </p> ';
    echo '<p> Description:'. $category->description . '</p>';
    echo '<p> Post Count: '. $category->count . '</p>';  
}

Yes, you can use get_categories() using 'child_of' attribute. For example all sub categories of category with the ID of 17:

$args = array('child_of' => 17);
$categories = get_categories( $args );
foreach($categories as $category) { 
    echo '<p>Category: <a href="' . get_category_link( $category->term_id ) . '" title="' . sprintf( __( "View all posts in %s" ), $category->name ) . '" ' . '>' . $category->name.'</a> </p> ';
    echo '<p> Description:'. $category->description . '</p>';
    echo '<p> Post Count: '. $category->count . '</p>';  
}

This will get all categories that are descendants (i.e. children & grandchildren).

If you want to display only categories that are direct descendants (i.e. children only) you can use 'parent' attribute.

$args = array('parent' => 17);
$categories = get_categories( $args );
foreach($categories as $category) { 
    echo '<p>Category: <a href="' . get_category_link( $category->term_id ) . '" title="' . sprintf( __( "View all posts in %s" ), $category->name ) . '" ' . '>' . $category->name.'</a> </p> ';
    echo '<p> Description:'. $category->description . '</p>';
    echo '<p> Post Count: '. $category->count . '</p>';  
}

** Solo un suggerimento: ** Con lapopolarità deitipi dipostpersonalizzatie delletassonomie,penso che sarebbemeglio suggerire `get_terms`,perché questo aiuta afamiliarizzaregli utenti con lefunzionigenerali di recupero deitermini,dove lefunzioni di categoria sono alquanto specificheallatassonomiaincorporata (sebbenenonin tuttii casi).Ovviamentenon deviessere d'accordo,è solo un suggerimento ...;)

**Just a suggestion:** With the popularity of custom post types and taxonomies, i feel it would be better to be suggesting `get_terms`, because this helps familiarise users with general term fetching functions, where as the category functions are somewhat specific to the built-in taxonomy(though not in all cases). You don't have to agree of course, it's just a suggestion... ;)

Sono d'accordo che [get_terms ()] (https://developer.wordpress.org/reference/functions/get_terms/)potrebbeesseremigliore.

I agree that [get_terms()](https://developer.wordpress.org/reference/functions/get_terms/) might be better.

please note, by default, this will not get you categories that has no post associated with them. use `hide_empty => false` to get all categories (as per the recent version of wordpress)
