jQuery UI sortable() - listitem jumps to top in Safari and Chrome

Question

I have a sortable unordered list on the bottom of my page, which works perfect in Firefox. However, in Safari/Chrome the grabbed listitem jumps instantly to the top of the page when I want to drag it, like the UL is on top of the window. Does anyone know what's going on here?

Thanks. Lex.

Here's the code:

HTML (and PHP):

<ul id="list">
    <?
        foreach($downloads as $download)
        {
            echo "<li class='downloads'><a rel='".$download->id."' href='".$base_url."downloads/".$download->id."'>".$download->title."</a></li>";
        }
    ?>
</ul>

CSS:

ul#list {
    padding: 10px 0;
    display: block;
}
ul#list li {
    background: #fff;
    padding: 10px;
    color: #bc1e2c;
    -moz-border-radius: 10px;
    -webkit-border-radius: 10px;
    font-weight: bold;
    margin: 10px 0;
    display: block;
}

ul#list li:hover {
    background: #212121;
    color: #fff;
    cursor: move;
}

JS:

$(".alter-content ul#list").sortable({
    update : saveSortorder,
    containment: 'parent'
});

Answer 1

I had the same problem. It worked well in Firefox but kept jumping in Safari and Chrome. I finally fixed it by adding overflow: auto; to the unsorted list in my CSS.

I didn't even have to specify the height of the UL.
