jQuery.naviDropDown
Simple jQuery Dropdown Menu with Easing and hoverIntent
Here is a simple jQuery plugin I wrote recently which allows you to create a simple drop down menu, utilising hoverIntent, and jQuery’s own slideUp and slideDown effects. You can also set the orientation of the drop down depending if your navigation is horizontal (default) or vertical, and set the duration and easing method of both slideUp and slideDown on initiation of the plugin.
The Plugin – jquery.naviDropDown:
Example below shows initiation of horizontal (default) and vertical orientations.
$(function(){
$('#navigation_horiz').naviDropDown({
dropDownWidth: '300px'
});
$('#navigation_vert').naviDropDown({
dropDownWidth: '300px',
orientation: 'vertical'
});
});Default operation (parameters):
For all the easing methods see jQuery Easing Plugin
dropDownClass: 'dropdown', //the class name for your drop down
dropDownWidth: 'auto', //the default width of drop down elements
slideDownEasing: 'easeInOutCirc', //easing method for slideDown
slideUpEasing: 'easeInOutCirc', //easing method for slideUp
slideDownDuration: 500, //easing duration for slideDown
slideUpDuration: 500, //easing duration for slideUp
orientation: 'horizontal' //orientation - either 'horizontal' or 'vertical'CSS:
For vertical orientation – just remove the float:left from the #navigation_vert ul li or check the example below. Also *display:inline-block; resolves the gap issues between list items in Internet Explorer 7, this is only needed for vertical orientation.

/* ----------------------------------------------------- */HTML:
The element for the drop down is .dropdown – which is set as a parameter into the plugin, but can be changed, you can place any html within this element, each dropdown element can have its own styles, you can see that I have individually styled them via the CSS above targeting its ID. (The third list item does not have a drop down attached to it in the examples).

</div><!-- .dropdown_menu -->
</li>
</ul>
</div><!-- #navigation_horiz -->Limitations:
The default width of each dropdown is set to auto, so the automatic width will adjust to the width of the button for which the drop down is applied to. The plugin does not automatically calculate the width of the dropdown based on what is within it. You can manually overide the width from initiation – this applies to horizontal and vertical orientation. This is a basic jquery drop down menu, which obviously could be expanded, but can be customised further using CSS.
