    <p>I have been working on a new drop-down control, using dropkick, and I have it working in Chrome/FF, but not in IE8, which is sadly still our target. I used a single-pixel background image with <code>background-repeat:repeat-y</code> and <code>background-size:x%</code> to get the desired effect.</p> <p>I discovered too late that IE8 does not support background-size and my question is this: <strong>How do I emulate this effect in IE8?</strong></p> <p>My first thought is with some weird z-indexing and variable-width divs inside the <code>li</code> tags and behind the <code>a</code> tags, but my attempts at that have had less than spectacular results (largely because I have a hard time understanding css positioning). I am not sure how much it complicates things that this control resides on a draggable and resizable jQuery dialog, but for the sake of this question we can assume it won't move or change.</p> <p>The end result is something like this:</p> <p><img src="https://i.imgur.com/FxMaOvY.png" alt="control image"></p> <p>The numbers in the parens as well as the fill percentage are filled in with the options via an AJAX call.</p> <p>The code generated for the faux-dropdown is along these lines (truncated list):</p> <pre><code>&lt;div class="dk_options" style="top: 19px;"&gt; &lt;ul class="dk_options_inner"&gt; &lt;li class=" "&gt; &lt;a style="background-size:0%;" data-dk-dropdown-value=""&gt;&amp;nbsp;&lt;/a&gt; &lt;/li&gt; &lt;li class="dk_option_current "&gt; &lt;a style="background-size:6.6666666666666666666666666700%;" data-dk-dropdown-value="08:30AM"&gt;8:30 AM (1)&lt;/a&gt; &lt;/li&gt; &lt;li class=" "&gt; &lt;a style="background-size:13.333333333333333333333333330%;" data-dk-dropdown-value="08:45AM"&gt;8:45 AM (2)&lt;/a&gt; &lt;/li&gt; &lt;li class=" "&gt; &lt;a style="background-size:100%;" data-dk-dropdown-value="09:00AM"&gt;9:00 AM (15)&lt;/a&gt; &lt;/li&gt; &lt;li class=" "&gt; &lt;a style="background-size:0%;" data-dk-dropdown-value="09:15AM"&gt;9:15 AM (1)&lt;/a&gt; &lt;/li&gt; &lt;li class=" "&gt; &lt;a style="background-size:6.6666666666666666666666666700%;" data-dk-dropdown-value="09:30AM"&gt;9:30 AM (1)&lt;/a&gt; &lt;/li&gt; &lt;/ul&gt; &lt;/div&gt; &lt;/div&gt; </code></pre> <p>And the relevant css is something like this:</p> <pre><code>.dk_options_inner li { background:white; } .dk_options a { background-image:url(./images/dot.png); background-repeat:repeat-y; } </code></pre>

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.
