Display current category without an active link in wp_list_categories

You can use get_the_category(); to display your category in menu

<?php
    $categories = get_the_category();
    $separator=" ";
    $output="";
    if($categories){
        foreach($categories as $category) {

    $output .= '<a " href="'.get_category_link( $category->term_id ).'" title="' . esc_attr( sprintf( __( "View all posts in %s" ), $category->name ) ) . '">'.$category->cat_name.'</a>'.$separator;
        }
    echo trim($output, $separator);
    }
?>  

I used the <a> tag you can remove it for link. I Hope it help you
