These changes require a Divi child theme. Please check the following article if you have not set a child theme yet: https://intercom.help/elegantthemes/faq-s-and-troubleshooting/how-to-make-a-child-theme
In the child theme folder create a new folder, for example
includes
folder.Now copy the
Divi/includes/builder/module/Portfolio.php
file into thechild-theme/includes/
folder.Rename the file to something else, for example:
custom-Portfolio.php
Open up the
custom-Portfolio.php
file and replace this code (the first line):
class ET_Builder_Module_Portfolio extends ET_Builder_Module_Type_PostBased {
with:
class custom_ET_Builder_Module_Portfolio extends ET_Builder_Module_Type_PostBased {
Also, replace this line:
$this->vb_support = 'on';
with:
$this->vb_support = 'off';
6. Next, open up functions.php file in your child theme folder and add the following code at the very bottom:
function custom_portfolio_setup() {
get_template_part( 'includes/custom-Portfolio' );
$custom_portfolio = new custom_ET_Builder_Module_Portfolio();
remove_shortcode( 'et_pb_portfolio' );
add_shortcode( 'et_pb_portfolio', array( $custom_portfolio, '_render' ) );
}
add_action( 'et_builder_ready', 'custom_portfolio_setup' );
function divi_custom_portfolio_class( $classlist ) {
$classlist['et_pb_portfolio']['classname'] = 'custom_ET_Builder_Module_Portfolio';
return $classlist;
}
add_filter( 'et_module_classes', 'divi_custom_portfolio_class' );
Now you are ready to customize the Portfolio module the way you need and keep the changes while updating/reinstalling the parent Divi theme.
