    2. COI can move the canvas in firefox in to specific area but not in specific postion in this area. also I can move it back to its postion. Using javascript. This will be done with firefox but chrome will show the highlight for the backgroung of the canvas during moving. Thanks for your replay.

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.
