By the simplest definition, Joomanager is a Joomla component that gives your site the ability to list multiple items in multiple categories in a directory layout. Items you could list could be for a portfolio, items for sale, etc. Joomanager allows for the creation of custom fields so you can have an unlimited number of attributes associated with a particular item. These attributes are defined in the administration area of the component and can be geared towards any type of site to make it your own; for example a site that sells/lists: cars, boats, motorcylces, houses and whatever else you can think of.
