    <ol> <li>In order to show an arrow over a google map you can create a <a href="http://google-maps-utility-library-v3.googlecode.com/svn/trunk/richmarker/examples/richmarker.html" rel="noreferrer">Rich Marker</a> that embed an image using the <a href="http://code.google.com/p/google-maps-utility-library-v3/" rel="noreferrer">google-maps-utility-library-v3</a>,</li> <li>Next apply a rotation in degree to the image element with css3 tranformations.</li> </ol> <p>In example :</p> <pre> <code> // content element of a rich marker var richMarkerContent = document.createElement('div'); // arrow image var arrowImage = new Image(); arrowImage.src = 'http://www.openclipart.org/image/250px/' + 'svg_to_png/Anonymous_Arrow_Down_Green.png'; // rotation in degree var directionDeg = 144 ; // create a container for the arrow var rotationElement = document.createElement('div'); var rotationStyles = 'display:block;' + '-ms-transform: rotate(%rotationdeg);' + '-o-transform: rotate(%rotationdeg);' + '-moz-transform: rotate(%rotationdeg);' + '-webkit-transform: rotate(%rotationdeg);' ; // replace %rotation with the value of directionDeg rotationStyles = rotationStyles.split('%rotation').join(directionDeg); rotationElement.setAttribute('style', rotationStyles); rotationElement.setAttribute('alt', 'arrow'); // append image into the rotation container element rotationElement.appendChild(arrowImage); // append rotation container into the richMarker content element richMarkerContent.appendChild(rotationElement); // create a rich marker ("position" and "map" are google maps objects) new RichMarker( { position : position, map : map, draggable : false, flat : true, anchor : RichMarkerPosition.TOP_RIGHT, content : richMarkerContent.innerHTML } ); </code> </pre>

    1. COThanks Sébastien. I've been looking for a quick and easy way to rotate a marker and this is, by far, the best option for me. A second thank you for a working example.

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.

SQuiL has stopped working due to an internal error.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
