Taxonomy Categories in Multiple Columns

I have tried a bunch of solutions and mostly have it working using this code:

<div class="category_widget_container">
<?php
		$categories = wp_list_categories( $args );
		if( count( $categories ) > 0 ) {
			$new_array =  partition( $categories, 3 );

if( $new_array ) {
				foreach( $new_array as $top_index ) {
					if( is_array( $top_index ) ) {
						echo '<ul>';
						foreach( $top_index as $cats ) {
							printf( '<li><a href="%s">%s</a></li>', get_term_link( $cats->slug, 'eventcategory' ), $cats->name  );
						}
						echo '</ul>';
					}
				}
			}
		}

		?></div>

CSS:

.category_widget_container{
	width: 100%;
}

.category_widget_container ul {
	float: left;
	width: 185px;
	margin-right: 5px;
}

But the formatting is all messed up. Not sure how to fix it. Can anyone help?
