Paper-items are simple list elements, ideally used in a paper-listbox or an element with role="listbox"

They can be styled using custom properties

To add a leading element, use a paper-icon-item with an item-icon attribute. This leading image can be an iron-icon, or any other regular element.

For two-line items, use a paper-item-body inside a paper-item or paper-icon-item

Complex layouts are usually a combination of all these elements

Paper-items can be used as links
