# Related Articles
Related articles are articles that are related in some way to the product being viewed.

RocketDirectory uses an auto association method to make the link between articles.  Properties are used and any article with a matching property is automatically asscoiated.

The display of related properties can be controlled by using property groups.

## Related Property Display

*Get a list of 4 related articles in **RANDOM** order.*  
```
var relatedArticles = articleData.GetRelatedArticles("",4);
```
*Get a list of articles that are only in the "related" property group*
```
var relatedArticles = articleData.GetRelatedArticles("related",4);
```
*Example of displaying related particles*
