    <p>First you need to set the origin of rotation to top-left and the rotate,</p> <pre><code>$("#child").css({ "-webkit-transform-origin": "top left", "-moz-transform-origin": "top left", "-o-transform-origin": "top left", "transform-origin": "top left", "transform" : "rotate("+ angle +"deg)" }); </code></pre> <p>This will rotate the element around its (top, left) point.</p> <p>But as you described in your case, you need the div to be always in top,left you need to do some math with bounds of the div.</p> <p>you can get the bounds using <code>document.getElementById(ele).getBoundingClientRect();</code></p> <p>Then you need to get the bounds of the div before and after it was rotated. Apply the math logic based on the current angle. Find the code here for your reference.</p> <pre><code>$(function(){ $("#child").draggable(); var angle = 0; $("#btn1").click(function(){ angle = angle + 90; if(angle == 360) { angle = 0 } // reset top left position to (0,0) $("#child").css({"top": "0px", "left": "0px"}); var preBounds = getBounds("child"); $("#child").css({ "-webkit-transform-origin": "top left", "-moz-transform-origin": "top left", "-o-transform-origin": "top left", "transform-origin": "top left", "transform" : "rotate("+ angle +"deg)" }); var currBounds = getBounds("child"); if(angle == 90) { $("#child").css({ "left": currBounds.left+Number(preBounds.left-currBounds.left)+"px"}); } else if(angle == 180) { $("#child").css({ "top": currBounds.top+Number(preBounds.top-currBounds.top)+"px","left":currBounds.width+"px"}); } else if(angle == 270) { $("#child").css({ "top": currBounds.height+"px"}); } }); }); function getBounds(ele){ var bounds = document.getElementById(ele).getBoundingClientRect(); console.log(bounds); //{left:bounds.left, top:bounds.top, right:bounds.right, bottom:bounds.bottom} return bounds; } </code></pre> <p>Check the <a href="http://jsfiddle.net/sesubash/uhxPM/2/" rel="nofollow">fiddle</a> of the same. Hope it helps</p>

    1. COThanks. But in your fiddle I found that increasing height it did n't work. It is going out of the box to the left.

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).
