    <p>This is not particularly difficult once you find <a href="https://stackoverflow.com/questions/2674392/how-to-access-google-maps-api-v3-markers-div-and-its-pixel-position">the relevant previous answer</a>.</p> <p>You need to convert the centre of the map to its world co-ordinates, find where the map needs to be centered to put the <em>apparent</em> centre where you want it, and re-centre the map using the <em>real</em> centre.</p> <p>The API will always centre the map on the centre of the viewport, so you need to be careful if you use <code>map.getCenter()</code> as it will return the real centre, not the apparent centre. I suppose it would be possible to overload the API so that its <code>getCenter()</code> and <code>setCenter()</code> methods are replaced, but I haven't done that.</p> <p>Code below. <a href="http://acleach.me.uk/gmaps/v3/map-offsetcentre.htm" rel="noreferrer">Example online</a>. In the example, clicking the button shifts the centre of the map (there's a road junction there) down 100px and left 200px.</p> <pre><code>function offsetCenter(latlng, offsetx, offsety) { // latlng is the apparent centre-point // offsetx is the distance you want that point to move to the right, in pixels // offsety is the distance you want that point to move upwards, in pixels // offset can be negative // offsetx and offsety are both optional var scale = Math.pow(2, map.getZoom()); var worldCoordinateCenter = map.getProjection().fromLatLngToPoint(latlng); var pixelOffset = new google.maps.Point((offsetx/scale) || 0,(offsety/scale) ||0); var worldCoordinateNewCenter = new google.maps.Point( worldCoordinateCenter.x - pixelOffset.x, worldCoordinateCenter.y + pixelOffset.y ); var newCenter = map.getProjection().fromPointToLatLng(worldCoordinateNewCenter); map.setCenter(newCenter); } </code></pre>

    2. COIs it possible to get this code to fire when the page loads so that the map shows as offset when first viewed?

    3. CO@DarrenCook: Of course. Just use this instead of `map.setCenter()`. All this code does is recalculate what the map is told do do, and then it does its own `map.setCenter()`.

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.
