    <p>What is happening is that you have two functions working against each other: </p> <p>The first function has an "if-else" statement and the second function as well. That means that each function does something EVERYTIME you scroll. There are multiple ways of solving this.</p> <p>The way I would solve it is using a variable and updating the constraints. </p> <p>Let's say we have a variable onScreen that has value 1 if the paragraph is on the screen and value 0 if it isn't:</p> <p>For example:</p> <pre><code>&lt;div style="height: 800px"&gt;Example of scroll with fadeIn, fadeOut. &lt;p style="margin-top:300px;"&gt;These paragraphs will go away when you have scrolled more than 10 pixels from the top. They will appear again when you have scrolled to a proximity of 50 pixels from the bottom. They will also appear if you go within a proximity of 10 pixels of the top again.&lt;/p&gt; &lt;/div&gt; </code></pre> <p>Now for the jQuery code:</p> <pre><code>var $onScreen = 1; $(window).scroll(function(){ if($(window).scrollTop() &lt; 10){ if ($onScreen == 0) { $("p:first").stop(true,true).fadeIn("slow", "linear"); $onScreen = 1; } } if($(window).scrollTop() &lt;= 20 &amp;&amp; $(window).scrollTop() &gt;= 10){ if ($onScreen == 1) { $("p:first").stop(true,true).fadeOut("slow", "linear"); $onScreen = 0; } } if ($(window).scrollTop() + $(window).height() &gt;= $(document).height() - 50) { if ($onScreen == 0) { $("p:first").stop(true,true).fadeIn("slow", "linear"); $onScreen = 1; } } }); </code></pre> <p>Now this is not the most concise way of doing it and I didn't mean to do so: by making the code a bit more extensive I hope you can follow why it works now and didn't work before (such that you actually learn from it).</p> <p>I prepared a live example for you on Fiddle: <a href="http://jsfiddle.net/ycCAb/4/" rel="nofollow">http://jsfiddle.net/ycCAb/4/</a></p> <p>I hope this answers your question. Good luck!</p>

    1. CONote that I made the example in such a way that quick scrolling is not allowed. So grab the scrollbar and slowly move it down to see the functions execute. For your usage: change the parameters of the fadeOut function to allow for quick scrolling (because currently it only has a margin of 10px). Good luck!

    2. COAwesome, thanks for all the help! Is it somehow possible to have the contents opacity dependent on the proximity to the top/bottom so that instead of one point being a trigger for the fade, it will only be at full opacity when you're all the way scrolled up/down and will have a range based on your position?

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.
