    <p>I currently work with canvas speech balloons. But because the balloon with the pointer is wrapped in a div, some links under it aren't click able anymore. I cant use extjs in this case. <a href="http://www.meindesign.net/tools/querstion3.php" rel="noreferrer">See basic example for my speech balloon tutorial</a> <strong>requires HTML5</strong> </p> <p>So I decided to collect all link coordinates from inside the balloons in an array.</p> <pre><code>var clickarray=[]; function getcoo(thatdiv){ thatdiv.find(".link").each(function(){ var offset=$(this).offset(); clickarray.unshift([(offset.left), (offset.top), (offset.left+$(this).width()), (offset.top+$(this).height()), ($(this).attr('name')), 1]); }); } </code></pre> <p>I call this function on each (new) balloon. It grabs the coordinates of the left/top and right/down corners of a link.class - additionally the name attribute for what to do if someone clicks in that coordinates and I loved to set a 1 which means that it wasn't clicked jet. And unshift this array to the clickarray. You could use push too.</p> <p>To work with that array:</p> <pre><code>$("body").click(function(event){ event.preventDefault();//if it is a a-tag var x=event.pageX; var y=event.pageY; var job=""; for(var i in clickarray){ if(x&gt;=clickarray[i][0] &amp;&amp; x&lt;=clickarray[i][2] &amp;&amp; y&gt;=clickarray[i][1] &amp;&amp; y&lt;=clickarray[i][3] &amp;&amp; clickarray[i][5]==1){ job=clickarray[i][4]; clickarray[i][5]=0;//set to allready clicked break; } } if(job.length&gt;0){ // --do some thing with the job -- } }); </code></pre> <p>This function proofs the coordinates of a body click event or whether it was already clicked and returns the name attribute. I think it is not necessary to go deeper, but you see it is not that complicate. Hope in was enlish...</p>

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.
