如何将下拉变量字段更改为woocommerce中的复选框字段

Question

这是woocommerce下拉选项的代码。如何将下拉选项更改为复选框选项？

<?php
    $selected = isset( $_REQUEST[ 'attribute_' . sanitize_title( $attribute_name ) ] ) ? wc_clean( stripslashes( urldecode( $_REQUEST[ 'attribute_' . sanitize_title( $attribute_name ) ] ) ) ) : $product->get_variation_default_attribute( $attribute_name );

    wc_dropdown_variation_attribute_options( array( 'options' => $options, 'attribute' => $attribute_name, 'product' => $product, 'selected' => $selected ) );

    echo end( $attribute_keys ) === $attribute_name ? apply_filters( 'woocommerce_reset_variations_link', '<a class="reset_variations" href="#">' . esc_html__( 'Clear', 'wow' ) . '</a>' ) : '';
?>
