display_random_featured_item - want to extend description snippet

Hi- I wish to display a longer snippet with the random featured item. The display_random_featured_item helper doesn't appear to have any arguments to adjust the number of characters. That didn't work. How do I do this?

In case anyone was confused, the sentence "That didn't work" wasn't meant to be part of my question. I had tried adding a snippet code without success.

You're correct, the display_random_featured_item helper doesn't allow you to configure this.

As an alternative, you can use the random_featured_item helper, which simply returns the item. You can then pass this item to the item helper and display the item in whatever way you want.
