## Tooltip Widget version added: 1.9

Description: Customizable, themeable tooltips, replacing native tooltips.

## Options

### contentType: Function() or String

Default: `function returning the title attribute`

The content of the tooltip.

When changing this option, you likely need to also change the `items` option.

Multiple types supported:

- Function: A callback which can either return the content directly, or call the first argument, passing in the content, e.g., for Ajax content.
- String: A string of HTML to use for the tooltip content.

Code examples:

Initialize the tooltip with the content option specified:

`$(` `".selector"` `).tooltip({ content:` `"Awesome title!"` `});`

Get or set the content option, after initialization:

`// getter` `var` `content = $(` `".selector"` `).tooltip(` `"option"``,` `"content"` `);` `// setter` `$(` `".selector"` `).tooltip(` `"option"``,` `"content"``,` `"Awesome title!"` `);`

### disabledType: Boolean

Default: `false`
Disables the tooltip if set to `true`.
Code examples:

Initialize the tooltip with the disabled option specified:

`$(` `".selector"` `).tooltip({ disabled:` `true` `});`

Get or set the disabled option, after initialization:

`// getter` `var` `disabled = $(` `".selector"` `).tooltip(` `"option"``,` `"disabled"` `);` `// setter` `$(` `".selector"` `).tooltip(` `"option"``,` `"disabled"``,` `true` `);`

### hideType: Boolean or Number or String or Object

Default: `null`
If and how to animate the hiding of the tooltip.
Multiple types supported:

- Boolean: When set to `false`, no animation will be used and the tooltip will be hidden immediately. When set to `true`, the tooltip will fade out with the default duration and the default easing.
- Number: The tooltip will fade out with the specified duration and the default easing.
- String: The tooltip will be hidden using the specified effect. The value can either be the name of a built-in jQuery animateion method, such as `"slideUp"`, or the name of a jQuery UI effect, such as `"fold"`. In either case the effect will be used with the default duration and the default easing.
- Object: If the value is an object, then `effect`, `duration`, and `easing` properties may be provided. If the `effect` property contains the name of a jQuery method, then that method will be used; otherwise it is assumed to be the name of a jQuery UI effect. When using a jQuery UI effect that supports additional settings, you may include those settings in the object and they will be passed to the effect. If `duration` or `easing` is omitted, then the default values will be used. If `effect` is omitted, then `"fadeOut"` will be used.

Code examples:

Initialize the tooltip with the hide option specified:

`$(` `".selector"` `).tooltip({ hide: { effect:` `"explode"``, duration: 1000 } });`

Get or set the hide option, after initialization:

`// getter` `var` `hide = $(` `".selector"` `).tooltip(` `"option"``,` `"hide"` `);` `// setter` `$(` `".selector"` `).tooltip(` `"option"``,` `"hide"``, { effect:` `"explode"``, duration: 1000 } );`

### itemsType: Selector

Default: `[title]`

A selector indicating which items should show tooltips. Customize if you're using something other then the title attribute for the tooltip content, or if you need a different selector for event delegation.

When changing this option, you likely need to also change the `content` option.

Code examples:

Initialize the tooltip with the items option specified:

`$(` `".selector"` `).tooltip({ items:` `"img[alt]"` `});`

Get or set the items option, after initialization:

`// getter` `var` `items = $(` `".selector"` `).tooltip(` `"option"``,` `"items"` `);` `// setter` `$(` `".selector"` `).tooltip(` `"option"``,` `"items"``,` `"img[alt]"` `);`

### positionType: Object

Default: `{ my: "left top+15", at: "left bottom", collision: "flipfit" }`

Configuration for the Position utility. The `of` property defaults to the target element, but can also be overriden.

Note: In 1.9.0, the default value was `{ my: "left+15 center", at: "right center", collision: "flipfit" }`, but this was changed to more closely match native tooltip positioning.

Code examples:

Initialize the tooltip with the position option specified:

`$(` `".selector"` `).tooltip({ position: { my:` `"left+15 center"``, at:` `"right center"` `} });`

Get or set the position option, after initialization:

`// getter` `var` `position = $(` `".selector"` `).tooltip(` `"option"``,` `"position"` `);` `// setter` `$(` `".selector"` `).tooltip(` `"option"``,` `"position"``, { my:` `"left+15 center"``, at:` `"right center"` `} );`

### showType: Boolean or Number or String or Object

Default: `null`
If and how to animate the showing of the tooltip.
Multiple types supported:

- Boolean: When set to `false`, no animation will be used and the tooltip will be shown immediately. When set to `true`, the tooltip will fade in with the default duration and the default easing.
- Number: The tooltip will fade in with the specified duration and the default easing.
- String: The tooltip will be shown using the specified effect. The value can either be the name of a built-in jQuery animateion method, such as `"slideDown"`, or the name of a jQuery UI effect, such as `"fold"`. In either case the effect will be used with the default duration and the default easing.
- Object: If the value is an object, then `effect`, `duration`, and `easing` properties may be provided. If the `effect` property contains the name of a jQuery method, then that method will be used; otherwise it is assumed to be the name of a jQuery UI effect. When using a jQuery UI effect that supports additional settings, you may include those settings in the object and they will be passed to the effect. If `duration` or `easing` is omitted, then the default values will be used. If `effect` is omitted, then `"fadeIn"` will be used.

Code examples:

Initialize the tooltip with the show option specified:

`$(` `".selector"` `).tooltip({ show: { effect:` `"blind"``, duration: 800 } });`

Get or set the show option, after initialization:

`// getter` `var` `show = $(` `".selector"` `).tooltip(` `"option"``,` `"show"` `);` `// setter` `$(` `".selector"` `).tooltip(` `"option"``,` `"show"``, { effect:` `"blind"``, duration: 800 } );`

### tooltipClassType: String

Default: `null`
A class to add to the widget, can be used to display various tooltip types, like warnings or errors.

This may get replaced by the classes option.

Code examples:

Initialize the tooltip with the tooltipClass option specified:

`$(` `".selector"` `).tooltip({ tooltipClass:` `"custom-tooltip-styling"` `});`

Get or set the tooltipClass option, after initialization:

`// getter` `var` `tooltipClass = $(` `".selector"` `).tooltip(` `"option"``,` `"tooltipClass"` `);` `// setter` `$(` `".selector"` `).tooltip(` `"option"``,` `"tooltipClass"``,` `"custom-tooltip-styling"` `);`

### trackType: Boolean

Default: `false`
Whether the tooltip should track (follow) the mouse.
Code examples:

Initialize the tooltip with the track option specified:

`$(` `".selector"` `).tooltip({ track:` `true` `});`

Get or set the track option, after initialization:

`// getter` `var` `track = $(` `".selector"` `).tooltip(` `"option"``,` `"track"` `);` `// setter` `$(` `".selector"` `).tooltip(` `"option"``,` `"track"``,` `true` `);`

## Overview

Tooltip replaces native tooltips, making them themable as well as allowing various customizations:

- Display other content than just the title, like inline footnotes or extra content retrieved via Ajax.
- Customize the positioning, e.g., to center the tooltip above elements.
- Add extra styling to customize the appearance, for warning or error fields.

A fade animation is used by default to show and hide the tooltip, making the appearance a bit more organic, compared to just toggling the visiblity. This can be customized with the `show` and `hide` options.

The `items` and `content` options need to stay in-sync. If you change one of them, you need to change the other.

In general, disabled elements do not trigger any DOM events. Therefore, it is not possible to properly control tooltips for disabled elements, since we need to listen to events to determine when to show and hide the tooltip. As a result, jQuery UI does not guarantee any level of support for tooltips attached to disabled elements. Unfortunately, this means that if you require tooltips on disabled elements, you may end up with a mixture of native tooltips and jQuery UI tooltips.

### Additional Notes:

- This widget requires some functional CSS, otherwise it won't work. If you build a custom theme, use the widget's specific CSS file as a starting point.

## Example:

#### Create a tooltip on the document, using event delegation for all elements with a title attribute.
