Hello There,
Thanks for writing in! Regretfully you cannot mixed the stack layouts. Each of the stacks ha a unique design and we do not have the option to mixed the stacks in the theme. To resolve your issue, since you have your child theme active and ready, please follow the following steps below:
1] Using Notepad or TextEdit or Sublime Text or any text editor, please create a new file in your local machine.
2] Insert the following code into that new file
<?php
// =============================================================================
// VIEWS/INTEGRITY/CONTENT-PORTFOLIO.PHP
// -----------------------------------------------------------------------------
// Portfolio post output for Integrity.
// =============================================================================
$archive_share = x_get_option( 'x_integrity_portfolio_archive_post_sharing_enable' );
?>
<article id="post-<?php the_ID(); ?>" <?php post_class(); ?>>
<?php if ( ! x_is_portfolio_item() ) : ?>
<div class="entry-featured">
<?php x_portfolio_item_featured_content(); ?>
</div>
<?php endif; ?>
<div class="entry-wrap cf">
<?php if ( x_is_portfolio_item() ) : ?>
<div class="entry-info">
<div class="entry-featured">
<?php x_portfolio_item_featured_content(); ?>
</div>
<header class="entry-header">
<h1 class="entry-title entry-title-portfolio"><?php the_title(); ?></h1>
<?php x_integrity_entry_meta(); ?>
</header>
<?php x_get_view( 'global', '_content', 'the-content' ); ?>
</div>
<div class="entry-extra">
<?php x_portfolio_item_tags(); ?>
<?php x_portfolio_item_project_link(); ?>
<?php x_portfolio_item_social(); ?>
</div>
<?php else : ?>
<header class="entry-header">
<h2 class="entry-title entry-title-portfolio">
<a href="<?php the_permalink(); ?>" title="<?php echo esc_attr( sprintf( __( 'Permalink to: "%s"', '__x__' ), the_title_attribute( 'echo=0' ) ) ); ?>"><?php x_the_alternate_title(); ?></a>
</h2>
<?php if ( $archive_share == '1' ) : ?>
<?php x_portfolio_item_social(); ?>
<?php endif; ?>
</header>
<?php endif; ?>
</div>
</article>
3] Save the file named as content-portfolio.php
4] Upload this file to your server in the child theme’s folder wp-content/themes/x-child/framework/views/integrity/
You may need to create the folder path since it does not exist in your child theme.
Hope this helps. Please let us know how it goes.
