    <p>I have a <a href="http://jqueryui.com/demos/draggable/" rel="noreferrer">jQuery UI draggable</a> and several separately-defined <a href="http://jqueryui.com/demos/droppable/" rel="noreferrer">droppables</a>. Because one of the droppables is configured <code>tolerance: 'intersect'</code>, it's possible for a draggable to be dropped on more than one kind of droppable at the same time.</p> <p>What's the best way to prevent the unintended droppables from firing? Basically, I'd like to prioritize the droppables so that the droppables with <code>tolerance: 'intersect'</code> don't get triggered if another droppable was triggered.</p> <p><strong>Update</strong> - More info to clarify things:</p> <ul> <li><p>All of the droppables are configured <code>tolerance: 'pointer'</code> except for one class of droppable with <code>tolerance: 'intersect'</code>.</p></li> <li><p>The reason one class of droppable has <code>tolerance: 'intersect'</code> is that the droppables are really narrow, and users have problems finding them with <code>tolerance: 'pointer'</code>.</p></li> <li><p>Moving the droppables further apart isn't an option.</p></li> <li><p>None of the droppables overlap, but the draggable is large enough to overlap a droppable with <code>tolerance: 'intersect'</code> while the mouse pointer is over another droppable with <code>tolerance: 'pointer'</code>. At most two droppables can be triggered at once in this way.</p></li> <li><p>The UI is laid out so the user's intentions can be determined by ignoring the <code>tolerance: 'intersect'</code> droppable if another droppable has been triggered; i.e. if the user moved the mouse pointer over a droppable with <code>tolerance: 'pointer'</code>, it's safe to assume that he/she intended to drop it there. Problem is, I can't figure out how to ignore the unwanted droppable.</p></li> </ul>

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.
