new FloatingTips('a'); // Title attribute will be used as tip.

// A customized tip for all <span class="custom"> elements
new FloatingTips('span.custom', {

	// Content can also be a function of the target element!
	content: function(e) { return 'I am ' + e.getSize().x + ' px wide! :)'; },

	position: 'bottom', // Bottom positioned
	center: false,      // Place the tip aligned with target
	arrowSize: 12,      // A bigger arrow!

});

Syntax:

#JS

var myTips = new FloatingTips(elements, options);

• elements: Elements that will trigger floating tips; can an be a string selector or an element collection.
• options: (object) Options for the class. They are all listed below.

Options:

• position: Tip position, can be "top", "right", "bottom", "left" or "inside" (default "top").
• fixed: If the tip should be placed in fixed position (default FALSE). This allows you to have tips on fixed elements, that do no scroll on page scrolling.
• center: If the tip will be placed centered on the target element (default TRUE).
• content: (string or function) If this is a string, the content of the tip will be the value of the target element attribute with that name (example "title", default); if this is a function, the content will be the value returned by the function, that can accept an argument that is the target element (see How to use or Demo).
• html: If the tooltip content must be interpreted as HTML code (default FALSE); if this is TRUE and content option is a function that returns an HTML element, inner HTML of that returned element is used as tip content.
• balloon: TRUE if the tip is a balloon with a small triangle pointing the target element (default TRUE).
• arrowSize: Size in pixel of the small triangle in the balloon (default 6).
• arrowOffset: Distance in pixel of the small triangle from the edge of the balloon when center option is FALSE (default 6).
• distance: Distance in pixel of the tip from the target element (default 3).
• motion: Distance in pixel that the tip will cover during in/out animation (default 6).
• motionOnShow: If the tip will animate when showing (default TRUE).
• motionOnHide: If the tip will animate when hiding (default TRUE).
• showOn: When to show the tip, can be any event of the target element (default "mouseenter"), or null when to never show the tip.
• hideOn: When to hide the tip, can be any event of the target element (default "mouseleave"), or null when to never hide the tip.
• hideOnTipOutsideClick: Will hide the tip if the mouse is clicked somewhere outside the tip itself or the triggering element (default FALSE). Especially useful for dialog-like tips which stay on the page until manual action.
• discrete: Whether to show only one tip of the same group at the same time (default FALSE). The "same group" is considered the elements which have been passed to the FloatingTips instance in the constructor or being attach()ed later on.
• showDelay: The delay the show event is fired (default 0).
• hideDelay: The delay the hide event is fired (default 0).
• className: The class name the tip container will get; necessary for styling (default "floating-tip").
• identifier: An identifier for the tip instance, will be added as class name to the outermost tooltip element.
• offset: An object like {x: 0, y: 0} (default), that specify the distance of the tip from its normal position.
• fx: An object for additional Fx options (default {'duration': 'short'}).

Events:

• show(tip, element): Fires when the tip appears. tip is the tip element, element is the target element.
• hide(tip, element): Fires when the tip disappears. tip is the tip element, element is the target element.

Methods:

• attach(elements): Adds other elements that will trigger floating tips; can an be a string selector or an element collection.
• detach(elements): Remove floating tips triggering from elements; can an be a string selector or an element collection.
• show(element): Manually show the tip on target element.
• hide(element): Manually hide the tip for element.
• toggle(element): Manually toggle the tip for element.

Element and Elements methods:

You can use some shortcut methods on Element and Elements for creating and showing tips.

#JS

$$('a').floatingTips(options); // Create tips
$('myLink').floatingTipsShow(); // Show one
var myTips = $('myLink').get('floatingTips'); // Get instance

• Elements.floatingTips(options): Creates a new instance of FloatingTips on elements.
• Element.floatingTips(options): Creates a new instance of FloatingTips on the element.
• Element.floatingTipsShow(): Show the tip on the element.
• Element.floatingTipsHide(): Hide the tip on the element.
• Element.floatingTipsToggle(): Toggles the tip on the element.
• Element.get('floatingTips'): Retrieves the instance of FloatingTips of the element.

FloatingTips.Dialog is an extra class that extends FloatingTips to let you create dialog boxes that appears near target element (for example, on an important link for asking for confirmation).
