Hello,

You can add more types of portfolio with more rows in portfolio.php but then you will need to customize them with css as well. The responsible block of code is this:

 <?php     	
            $grid = 'three-cols';
		    switch($onero_redata['portfolio_columns']){
		        case '3':
		            $grid = 'three-cols';
		            break;
		        case '2':
		            $grid = 'two-cols';
		            break;
		        case '4':
		            $grid = 'four-cols';
		            break;
                case '5':
                    $grid = 'five-cols';
                    break;
		        case '1':
		            $grid = 'one-cols';
		            break;
		    }
    	?>

This is not recommended but your are free to edit theme as you wish.
To be able to always get necessary updates, we recommend to use a child theme to keep all the edited files. So you won’t have to redo them in every theme update.
Please keep in mind that personal customization are not included in support service.

Best regards!

Hello,

Onero comes with the child theme included in it’s package. Just make sure to have added the child theme too, in your wp-content/themes folder. Using WordPress dashboard or uploading it directly via ftp. Then go to your Appearance > Themes and activate it as a normal theme.
Just make sure to have Onero parent theme installed as well or it will not work.
Let us know.

Best regards!
