    <p>I'm building a poker table maker that works as follows:</p> <ol> <li>When the page loads, I load the components of a poker table one-by-one. </li> <li>Final users select what kind of felt, armrest, body or cup holders want on their poker tables through a select box. </li> <li>When a change is detected in the select box, the src attribute of the Image object changes as well. For example: If a user wants a black felt, I'm loading the image: felts/black.png; then if he decides that it looks better in blue, the page loads the image felts/blue.png</li> </ol> <p>My problem is the following:</p> <p>As soon as they change one element of the poker table, the new image is automatically loaded on top of the rest .</p> <p>For example: If I change the felt color, the felt's image will go on top of the armrest's image. </p> <p>I'd like to know how to force the felt image to maintain its z-index sort of thing. </p> <p>Here's my code:</p> <pre><code> var tableBody = new Image(); tableBody.onload = function() { context.drawImage(tableBody, 0, 0); }; tableBody.src = "http://www.mcptables.com/images/buildyourtable/body/autumn-oak.png"; /* and it does the same thing for the other parts of the poker table... tableArmrest, tableFelt tableCupholders, etc... */ $('#armrest').change( function() { switch( $(this).val() ) { case "black": tableArmrest.src = "http://www.mcptables.com/images/buildyourtable/armrest/black.png"; break; case "brown": tableArmrest.src = "http://www.mcptables.com/images/buildyourtable/armrest/wood.png"; } } ) </code></pre> <p>You can see it in action on the following page:</p> <p><a href="http://mcptables.com/buildyourtable.html" rel="nofollow">http://mcptables.com/buildyourtable.html</a></p> <p>And here's a link to my JS code:</p> <p><a href="http://mcptables.com/js/pokertablebuilder.js" rel="nofollow">http://mcptables.com/js/pokertablebuilder.js</a></p> <p>Any help would be greatly appreciated!

    1. COYou could use an array to determine which image should be reloaded using a specific order (Body first, then Armrest ...). I don't think that there's anything like z-index in canvas

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.
