You don't need JavaScript for the hover. Make an element that serves as your tooltip and position it above your dropdown button. Then make a parent <div>
for both. Your HTML should look something like this:
<div id="container">
<div id="button">...</div>
<div id="tooltip">...</div>
</div>
Once you've done that, you can use CSS to position the tooltip and show it when necessary.
#container {
/* All child elements should be positioned relative to this one. */
position: relative;
}
#container #tooltip {
/* Hide by default. */
display: none;
/* Place the tooltip 2px above the button. */
position: absolute;
bottom: 2px;
right: 0px;
}
#container #button:hover + #tooltip {
/* Show it when someone's hovering over the button. */
display: block;
}
To show the drop-down box, you probably will need JavaScript. Add another element to the container:
<div id="container">
<div id="button">...</div>
<div id="tooltip">...</div>
<ul id="selection">
<li>Something</li>
<li>Something Else</li>
<li>A Third Thing</li>
</ul>
</div>
Position it as you like using position: absolute
and hide it using display: none
. Then show it when we click on the button:
$('#button').click(function() {
$('#selection').show();
});
You can then make your sub-items do whatever they like, as long as they also hide #selection
.
$('#selection li').click(function() {
// do something
$('#selection').hide();
});
Finally, you want to change the background and text colours upon hover. That's easy enough:
#selection li {
background-color: #ccc;
color: black;
}
#selection li:hover {
background-color: black;
color: white;
}
This won't work perfectly in IE 6 or (I believe) 7 - you'll need to investigate alternative solutions for that. Either use JavaScript or check out IE7.js and IE8.js.
