    <p>I am trying to make a jquery modal dialog. (please do not say "use a plugin").</p> <p>I am well aware that the js I am using is crap, once I am trying to hack together the basic functionality, once I have the basic functionality down I will rewrite this as a jquery plugin for my own use.</p> <p>Anyway,</p> <p>I have got the dialog appearing, and it is in the center of the page, The dialog is sized by its content.</p> <p>In this specific example the content has a fixed width.</p> <p>I am trying to handle the case where the content is bigger that the page width.</p> <p>I am getting a strange issue where, if the page is resized the content seems to literally just be cut off, no scroll bars.</p> <p>What could be my issue?</p> <p><strong>Example:</strong> <a href="http://jsbin.com/egowo3/edit" rel="nofollow">http://jsbin.com/egowo3/edit</a><br> <strong>CSS:</strong> </p> <pre><code>body { padding: 0; margin: 0; color: #fff; } #overlay { position:fixed; width:100%; height:100%; background: rgba(0,0,0,0.8); z-index: 9999; display: none; } #dialog { display: none; background: #000; border: 1px solid #0000ff; position: fixed; z-index: 99999; } #test { display: none; width: 1300px; } </code></pre> <p><strong>Javascript</strong> </p> <pre><code>$(function(){ $('button').click(function(){ var body = $('body'); var content = $('#test'); var dialog = $('&lt;div id="dialog"&gt;&lt;/div&gt;'); var overlay = $('&lt;div id="overlay"&gt;&lt;/div&gt;'); var width = content.outerWidth(true); var height = content.outerHeight(true); body.prepend(dialog); body.prepend(overlay); dialog.prepend(content) .height(height) .width(width); content.show(); var left = (overlay.width()/2)-(dialog.outerWidth()/2); var top = (overlay.height()/2)-(dialog.outerHeight()/2); dialog.css({ left : left, top : top }); overlay.fadeIn('fast'); dialog.fadeIn('fast'); $(window).resize(function() { overlay = $('#overlay'); dialog = $('#dialog'); if(overlay.length == 0 || dialog.length == 0) return false; var left = (overlay.width()/2)-(dialog.outerWidth()/2); var top = (overlay.height()/2)-(dialog.outerHeight()/2); dialog.css({ left : left, top : top }); }); }); }); </code></pre> <p><strong>HTML</strong></p> <pre><code>&lt;body&gt; &lt;button&gt;Modal Me&lt;/button&gt; &lt;div id="test"&gt; &lt;p&gt;Pid ac lundium urna tempor vut, elementum adipiscing mauris, magna cum odio!

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.
