Simple and clean wordpress custom post query

custompostquery.php

<ul>
<?php
    $wp_query = new WP_Query( array(
        'post_type' => 'gallery',
        'posts_per_page' => -1
    ));
     
    if( have_posts() ) { 
        while ( $wp_query->have_posts() ) {
            $wp_query->the_post();
            echo '<li>' . the_title() . '</li>';
        }
    }
    else {
        echo '<li>No Title</li>';
    } 
    wp_reset_query();
?>
</ul>

Change the 'posts_per_page' from 100 to -1 to default to show all posts vs a random number

Realized that I didn't have a unordered list element for the list item to be contained in.

"the_title()" echoes itself out. Please try "get_the_title()"
