Add news slider/carousel to Service Box

Hello!

I’m trying to add a slider or a carousel displaying latest post from a category into a Service Box.

I’ve hard coded using PHP, because the text editor in Abaris admin doesn’t allow PHP and it doesn’t work with shortcodes.

But, if i try to insert into front-page.php some custom code, I alway get this code back outside the service div. That happens not when i’m using php echo, but for example if i call a WP function like the_widget(‘NAME OF WIDGET’);

And it is a bad issue.

Any suggestion? Thanks
