Sim,vocêpode usar get_categories () 'child_of' atributo. Porexemplo,todas as sub-categorias de categoria com o ID de 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>';  
}

Isso obterátodas as categorias que são descendentes (isto é,crianças & amp;netos).

Se você quiserexibir apenas as categorias que são descendentes diretas (somentefilhos) Vocêpode usar o atributo '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>';  
}

** Apenas uma sugestão: ** Com apopularidade dostipospersonalizadose taxonomias,sinto que seriamelhor ser sugerindo "get_terms",porqueisso ajuda afamiliarizar os usuários comfunções debusca determogeral,onde asfunções da categoria são umpoucoespecíficaspara ataxonomiaembutida (emboranãoem todos os casos).Vocênãoprecisa concordar,é claro,é apenas uma sugestão ...)

**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... ;)

Eu concordo que [get_terms ()] (https://developer.wordpress.org/reference/functions/get_terms/)pode sermelhor.

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

Porfavor,note,porpadrão,issonão receberá as categorias quenãotem post associada aelas.Use `hide_empty=>false`para obtertodas as categorias (conforme a versão recente do WordPress)

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)
