FIlter to change category title to h2

Hi there,

Do you mean the category title on the category archive page?

The easiest option is to create a block element – page hero for the category archives.

Then you can define the category title as h2.

Here’s a screenshot for the H2 title configuration:

Here’s a screenshot for the description configuration:

Let me know if this helps!

There isn’t an easy filter for this, here’s the functions you will need to change it from h1 to h2:

function remove_generate_archive_title() {
    remove_action( 'generate_archive_title', 'generate_archive_title', 10 );
}
add_action( 'after_setup_theme', 'remove_generate_archive_title' );

function h2_archive_title() {
    ?>
    <header <?php generate_do_attr( 'page-header' ); ?>>
        <?php
        /**
         * generate_before_archive_title hook.
         *
         * @since 0.1
         */
        do_action( 'generate_before_archive_title' );
        ?>

        <h2 class="page-title">
            <?php the_archive_title(); ?>
        </h2>

        <?php
        /**
         * generate_after_archive_title hook.
         *
         * @since 0.1
         *
         * @hooked generate_do_archive_description - 10
         */
        do_action( 'generate_after_archive_title' );
        ?>
    </header>
    <?php
}
add_action( 'generate_archive_title', 'h2_archive_title', 10 );
