Try this: First of all, make sure you are using a OpenLayers.Layer.Vector layer, not a OpenLayers.Layer.Markers layer. Apparently the Markers layer is old news and all new development is done in the Vector layer. It has more features. (I wasted a pile of time with the Markers layer myself). Then, each of your markers needs to be a OpenLayers.Feature.Vector object. The constructor takes three arguments, the third of which is called the style. The style is where you set your image attributes, the background shadow, the mouse-over text, and the z-index, which has the property name "graphicZIndex". I think that's what you're looking for. <a href="http://dev.openlayers.org/releases/OpenLayers-2.12/doc/apidocs/files/OpenLayers/Feature/Vector-js.html#OpenLayers.Feature.Vector.OpenLayers.Feature.Vector.style" rel="nofollow">http://dev.openlayers.org/releases/OpenLayers-2.12/doc/apidocs/files/OpenLayers/Feature/Vector-js.html#OpenLayers.Feature.Vector.OpenLayers.Feature.Vector.style</a> Add your "markers" (which are Vector's) to your Vector layer with the addFeatures function. And just ignore the "options" argument. <a href="http://dev.openlayers.org/releases/OpenLayers-2.12/doc/apidocs/files/OpenLayers/Layer/Vector-js.html#OpenLayers.Layer.Vector.addFeatures" rel="nofollow">http://dev.openlayers.org/releases/OpenLayers-2.12/doc/apidocs/files/OpenLayers/Layer/Vector-js.html#OpenLayers.Layer.Vector.addFeatures</a> I found that example page too, and I found it confusing too. It was setting all the markers' styles in the Vector layer's constructor (as default values to be used if the marker style was omitted) instead of the marker's constructor. I think it makes more sense to set the marker style in the marker constructor. To change the style in real-time, take one of your OpenLayers.Feature.Vector markers, called "marker" and do this. And let's call the Vector Layer "layer". <pre><code>marker.style.graphicZIndex = 13; layer.redraw(); </code></pre>

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.
