Default categories are populated like this →

<?php
                if( $terms = get_terms( 'category', 'orderby=name' ) ) : // to make it simple I use default categories
                    echo '<select name="categoryfilter"><option value="all">All</option>';
                    foreach ( $terms as $term ) :
                        echo '<option value="' . $term->slug . '">' . $term->name . '</option>'; // ID of the category as the value of an option
                    endforeach;
                    echo '</select>';
                endif;
            ?>

enter image description here

I tried to put vcategory instead of category, but it didn't work.

The second param fort historia function is deprecated, so it would be much nicer to pass params as an array:

$terms = get_terms( array(
    'taxonomy' => 'vcategory',
    'hide_empty' => false,

) );

But if you want to show a select filled with terms of given taxonomy, there’s a function for that:

wp_dropdown_categories( array(
    'show_option_all'    => 'All',
    'orderby'            => 'name',
    'order'              => 'ASC',
    'hide_empty'         => 1, // change to 0 if empty terms should be shown to
    'echo'               => 1,
    'selected'           => 0,
    'name'               => 'categoryfilter',
    'taxonomy'           => 'vcategory',
    'value_field'        => 'slug',
) );
