Make a vertical dynamic list of posts in alphabetically order and in columns [closed]

Question

You can just simply create a custom query with WP_Query. You just need to make sure if you are using a custom taxonomy or the build-in category. For reference, see: Is There a Difference Between Taxonomies and Categories?

Here is an example for custom taxonomies (this can also be used for build-in categories, just change 'taxonomy' => 'MY_CUSTOM_TAXONOMY', to 'taxonomy' => 'category',):

$args = array(
    'post_type' => 'MY_CUSTOM_POST_TYPE',
    'posts_per_page' => -1,
    'orderby' => 'title',
    'order' => 'DESC',
    'tax_query' => array(
        array(
            'taxonomy' => 'MY_CUSTOM_TAXONOMY',
            'field'    => 'slug',
            'terms'    => 'THE_SLUG_FROM_MY_TERM',
        ),
    ),
);

$the_query = new WP_Query( $args );

// The Loop
    echo '<ul>';
    while ( $the_query->have_posts() ) {
        $the_query->the_post();
        echo '<li>' . get_the_title() . '</li>';
    }
    echo '</ul>';

/* Restore original Post Data */
wp_reset_postdata();

For a single term, you can also work directly with the query vars, so you can change your $args to something like this

$args = array(
    'post_type' => 'MY_CUSTOM_POST_TYPE',
    'posts_per_page' => -1,
    'orderby' => 'title',
    'order' => 'DESC',
    'MY_CUSTOM_TAXONOMY'    => 'THE_SLUG_FROM_MY_TERM',
);

If you have a built-in category, change your $args to the following

$args = array(
    'post_type' => 'MY_CUSTOM_POST_TYPE',
    'posts_per_page' => -1,
    'orderby' => 'title',
    'order' => 'DESC',
    'cat'    => 'THE_ID_OF_YOUR_CATEGORY',
);
