Repost: How to disable Title, Category and Tag in DWQA

If you want to remove the Title, Category, and Tag in your ask question page, you can open the Handle.php and question-submit-form.php files.
+ In the Handle.php file you can remove the line code: 373, 398, 443.
+ In the question-submit-form.php file, you can replace the code in your file with the following code:

<?php
/**
 * The template for displaying single answers
 *
 * @package DW Question & Answer
 * @since DW Question & Answer 1.0.1
 */
?>
 <?php do_action( 'dwqa_before_question_submit_form' ); ?>
<?php if ( dwqa_current_user_can( 'post_question' ) ) : ?>
 <form method="post" class="dwqa-content-ask-form">
 <p class="dwqa-search">
 <label for="question_title"><?php _e( 'Title', 'dwqa' ) ?></label>
 <?php $title = isset( $_POST['question-title'] ) ? $_POST['question-title'] : ''; ?>

Thanks for your answer. Is there a possibility to disable title through CSS rather than PHP files.
