Slats are used to group information that are relevant only to itself. Slats should not be used to compare data with other slats - use a table for that. Unlike a table, slats do not necessarily have to hold the same amount of information as each other which gives it more flexibility when displaying data.
The content within is often variable so there are no specific markup rules to follow apart from the outer shell (ie)
<ul class="slat-list"><ul>. However most slat listings have a heading or title and an action button to the far right.
