Body
There are three ways to do that: <ol> <li>Use a CompositeCell with an ClickTextCell and a SelectionCell and override the render method of the CompositeCell to render only the ClickTextCell. When the ClickTextCell is clicked it will automatically call the ValueUpdater. In the update function of the ValueUpdater you have to set some boolean value in your ClickTextCell. Then you have to check in the render method of your CompositeCell this boolean value and if it is set, then render the SelectionCell instead of the ClickTextCell. </li> <li>Create a custom cell extending AbstractEditableCell for example (see this <a href="http://code.google.com/webtoolkit/doc/latest/DevGuideUiCustomCells.html" rel="nofollow">tutorial</a>) and implement the functionality yourself. You can check out the code for <a href="http://www.google.com/codesearch#A1edwVHBClQ/user/src/com/google/gwt/cell/client/SelectionCell.java&q=SelectionCell%20package%3ahttp://google-web-toolkit%5C.googlecode%5C.com" rel="nofollow">SelectionCell</a> and <a href="http://www.google.com/codesearch#A1edwVHBClQ/user/src/com/google/gwt/cell/client/EditTextCell.java" rel="nofollow">EditTextCell</a> and copy most of it. Basically you have to have some kind of a flag which is set when the cell gets focus. In the render method you have to either display a dropdownlist or just a text. </li> <li>Extend either EditTextCell or SelectionCell and implement the missing functionality. The advantage is that you can probably re-use some of the render methods and you don't have to write the complete render code yourself. </li> </ol>

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.
