    text
    <p>I have a div that is centered on the page using css - margin: 0 auto; This is essential</p> <p>jQuery resizeable is connected to the div so that it can be resized horizontally. </p> <p>The 'grid' option for resizeable has also been added as other functions are triggered during resize and these functions were being called too many times without the grid option activated.</p> <p>i have also added a jquery position to the resizable div to keep it centered during resize otherwise when you drag the left edge it loses it's center position.</p> <p>The problem is that the mouse moves further and further away from the left edge the wider you drag the div to the left or right. The left/right edge of the div should always be snapping to the mouse position.</p> <p>Also the ui.size.width is reporting a value much higher than the actual width of the div.</p> <p>I have tried numerous fixes but nothing seems to work.</p> <p>Here's the code with a jsfiddle link below it:</p> <p>The HTML:</p> <pre><code>&lt;div id="container"&gt; &lt;div class="resize"&gt; Lorem &lt;br/&gt;ipsum &lt;br/&gt;dolor &lt;br/&gt;sit &lt;br/&gt;amet &lt;br/&gt;Consectetuer &lt;br/&gt;Lorem &lt;br/&gt;magna &lt;br/&gt;mi &lt;br/&gt;wisi &lt;/div&gt; &lt;/div&gt; &lt;div id="width-output"&gt;&lt;/div&gt; &lt;div id="ui-width-output"&gt;&lt;/div&gt; </code></pre> <p>The CSS:</p> <pre><code>#container { width:100%; background-color:#999999; } .resize { width:240px; margin:0 auto; background-color:#ccc; text-align:center; } #ui-width-output, #width-output { text-align:center; } </code></pre> <p>The jQuery:</p> <pre><code>$(document).ready(function () { $(".resize").resizable({ grid: [80, 80], handles: 'e, w', resize: function (event, ui) { ui.size.width += ui.size.width - ui.originalSize.width; var container = $('#container'); var position = $(this).position(); var container_position = container.position(); var top_position = position.top - container_position.top; var offset = 'center top+' + top_position; $(this).position({ of: $(container), my: offset, at: "center top", collision: "fit none" }); $('#width-output').html('actual width: ' + $(this).width() ); $('#ui-width-output').html('ui.size.width: ' + ui.size.width); } }); }); </code></pre> <p>I have created a test case so that all this makes more sense!</p> <pre><code>http://jsfiddle.net/bennyticklez/S5tN8/51/ </code></pre> <p>Thanks in advance.</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.
