    <p>I’m starting to develop my first full-blown Cocoa application containing a view which I would like to behave (and look) similar to Automator’s <code>AMWorkflowView</code>. </p> <p>The basic features I’d like to achieve:</p> <ul> <li>Positioning of subviews</li> <li>Display of subviews in expanded / collapsed states</li> <li>Multiple selection</li> <li>Drag and drop</li> </ul> <p>In order to get accustomed to Cocoa, I started with a custom <code>NSView</code> which mainly served as a container for the custom subviews and handled their positioning and multiple selection. The subviews are also subclasses of <code>NSView</code>, and contain a variable amount of views themselves, like buttons, labels and popup menus, and therefore can have different heights. This worked quite well, but before going on, I want to make sure to have everything neat and tidy according to the MVC pattern. </p> <p>I suspect that there already is a class in Cocoa that facilitates the implementation of a view container, like maybe <code>NSCollectionView</code>. <a href="https://stackoverflow.com/questions/2308798/is-there-a-way-to-have-varying-views-in-an-nscollectionview">It seems that there is no (easy) way</a> to display differently sized views in an <code>NSCollectionView</code>, though. Should I continue implementing my custom <code>NSView</code> (probably using an <code>NSArrayController</code> for selection and sorting support), or are there better ways to go?</p> <p>Any help is much appreciated</p>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
