Bootstrap 3 Typeahead
=====================

For simple autocomplete use cases there seems to be nothing wrong with the dropped typeahead plugin. Here you will find the typeahead autocomplete plugin for Twitter's Bootstrap 2 ready to use with Twitter's Bootstrap 3. The original code is written by @mdo and @fat.

Users who migrate their website or app from Twitter's Bootstrap 2 to Bootstrap 3 can also use this plugin to keep their current autocomplete functions. See for a complete list of migrations steps: Migrate your templates from Twitter Bootstrap 2.x to Twitter Bootstrap 3

With Twitter Bootstrap 3 the typeahead plugin had been dropped. @mdo says: "in favor of folks using Twitter's typeahead. Twitter's typeahead has more features than the old bootstrap-typeahead.js and less bugs." Twitter's typeahead don't work direct with Bootstrap 3. The DOM structure of the dropdown menu used by typeahead.js differs from the DOM structure of the Bootstrap dropdown menu. You'll need to load some additional CSS in order to get the typeahead.js dropdown menu to fit the default Bootstrap theme. Try extended Bootstrap LESS or if your are looking for a more extended version try: typeahead.js-bootstrap3.less.

~~Typeahead.js doesn't seem ready for the new Twitter Bootstrap 3 at the moment. Code is not up to date and fixes are needed. See also:
Typeahead problems with Bootstrap 3.0 RC1.~~

Bootstrap 4
===========
Bootstrap 4 is coming soon. The Bootstrap 3 Typeahead will also work with Bootstrap 4.
The look and feel of Bootstrap 4 will differ from Bootstrap 3 and so does the drop down menu. In Bootstrap 4 the typeahead dropdown menu will look like that shown in the figure below:
!Bootstrap 4 Typeahead.

Download
========

- Download the latest bootstrap3-typeahead.js or bootstrap3-typeahead.min.js.

- Include it in your source after jQuery and Bootstrap's JavaScript.

Full integration with Bootstrap 3 Typeahead
-------------------------------------------
Download the latest version of Boostrap from Bootstrap. Copy bootstrap3-typeahead.js to the js/ folder. Edit gruntfile.js and add bootstrap3-typeahead.js to the plugins list.
Build your own version with typeahead with grunt dist.

CSS
===
There is no additional CSS required to use the plugin. Bootstrap's CSS contains all required styles in the .dropdown-menu class. The original CSS adds a z-index of 1051 to the dropdownmenu via the typeahead class. You could add this if you need it.
.typeahead { z-index: 1051; } (less or css).

Usage
=====

You'll want to set autocomplete="off" to prevent default browser menus from appearing over the Bootstrap typeahead dropdown.

Via data attributes
-------------------
Add data attributes to register an element with typeahead functionality as shown in the example above.

Via JavaScript
--------------

Call the typeahead manually with:

$('.typeahead').typeahead()

Destroys previously initialized typeaheads. This entails reverting DOM modifications and removing event handlers:

$('.typeahead').typeahead('destroy')

Javascript Example
=============

Loading a collection
--------------------

$.get('example_collection.json', function(data){
$("#name").typeahead({ source:data });
},'json');
//example_collection.json
// ["item1","item2","item3"]

Using JSON objects instead of simple strings
--------------------------------------------

You can add all the properties you wish on your objects, as long as you provide a "name" attribute OR you provide your own displayText method. The other values allow you to match the selected item with something in your model.

var $input = $('.typeahead');
$input.typeahead({source:[{id: "someId1", name: "Display name 1"},
{id: "someId2", name: "Display name 2"}],
autoSelect: true});
$input.change(function() {
var current = $input.typeahead("getActive");
if (current) {
// Some item from your model is active!
if (current.name == $input.val()) {
// This means the exact match is found. Use toLowerCase() if you want case insensitive match.
} else {
// This means it is only a partial match, you can either add a new item
// or take the active if you don't want new items
}
} else {
// Nothing is active so it is a new value (or maybe empty value)
}
});

Options
=======

Options can be passed via data attributes or JavaScript. For data attributes, append the option name to data-, as in data-source="".

Name	Type	Default	Description
source	array, function	[ ]	The data source to query against. May be an array of strings, an array of JSON object with a name property or a function. The function accepts two arguments, the `query` value in the input field and the `process` callback. The function may be used synchronously by returning the data source directly or asynchronously via the `process` callback's single argument.
items	number	8	The max number of items to display in the dropdown. Can also be set to 'all'
minLength	number	1	The minimum character length needed before triggering autocomplete suggestions. You can set it to 0 so suggestion are shown even when there is no text when lookup function is called.
showHintOnFocus	boolean or "all"	false	If hints should be shown as soon as the input gets focus. If set to true, all match will be shown. If set to "all", it will display all hints, not filtering them by the current text. This can be used when you want an input that behaves a bit like a combo box plus auto completion as you type to filter the choices.
scrollHeight	number, function	0	Number of pixels the scrollable parent container scrolled down (scrolled out the viewport).
matcher	function	case insensitive	The method used to determine if a query matches an item. Accepts a single argument, the `item` against which to test the query. Access the current query with `this.query`. Return a boolean `true` if query is a match.
sorter	function	exact match, case sensitive, case insensitive	Method used to sort autocomplete results. Accepts a single argument `items` and has the scope of the typeahead instance. Reference the current query with `this.query`.
updater	function	returns selected item	The method used to return selected item. Accepts a single argument, the `item` and has the scope of the typeahead instance.
highlighter	function	highlights all default matches	Method used to highlight autocomplete results. Accepts a single argument `item` and has the scope of the typeahead instance. Should return html.
displayText	function	item.name \|\| item	Method used to get textual representation of an item of the sources. Accepts a single argument `item` and has the scope of the typeahead instance. Should return a String.
autoSelect	boolean	true	Allows you to dictate whether or not the first suggestion is selected automatically. Turning autoselect off also means that the input won't clear if nothing is selected and `enter` or `tab` is hit.
afterSelect	function	$.noop()	Call back function to execute after selected an item. It gets the current active item in parameter if any.
delay	integer	0	Adds a delay between lookups.
appendTo	jQuery element	null	By defaut, the menu is added right after the input element. Use this option to add the menu to another div. It should not be used if you want to use bootstrap dropup or dropdown-menu-right classes.
fitToElement	boolean	false	Set to true if you want the menu to be the same size than the input it is attached to.
addItem	JSON object	false	Adds an item to the end of the list, for example "New Entry". This could be used, for example, to pop a dialog when an item is not found in the list of data. Example: http://cl.ly/image/2u170I1q1G3A/addItem.png

Methods
=======

.typeahead(options): Initializes an input with a typeahead.
.lookup: To trigger the lookup function externally
.getActive: To get the currently active item, you will get a String or a JSON object depending on how you initialized typeahead. Works only for the first match.

Bower
=====

To use with Bower. Add to your bower.json file:

{
"name": "MyProject",
"dependencies": {
"bootstrap3-typeahead": "git://github.com/bassjobsen/Bootstrap-3-Typeahead.git#master"
}
}

AngularJS
=========
An AngularJS directive for the Bootstrap 3 Typeahead jQuery plugin can be found at https://github.com/davidkonrad/angular-bootstrap3-typeahead.

Bloodhound
==========
Bloodhound is the typeahead.js suggestion engine, since version 0.10.0. Bloodhound is robust, flexible, and offers advanced functionalities such as prefetching, intelligent caching, fast lookups, and backfilling with remote data. To use Bloodhound with Bootstrap-3-Typeahead:

// instantiate the bloodhound suggestion engine
var numbers = new Bloodhound({
datumTokenizer: Bloodhound.tokenizers.whitespace,
queryTokenizer: Bloodhound.tokenizers.whitespace,
local: ["(A)labama","Alaska","Arizona","Arkansas","Arkansas2","Barkansas"]
});

// initialize the bloodhound suggestion engine
numbers.initialize();

$('.typeahead').typeahead(
{
items: 4,
source:numbers.ttAdapter()
});

Bootstrap Tags Input
====================
Bootstrap Tags Input is a jQuery plugin providing a Twitter Bootstrap user interface for managing tags. Bootstrap Tags Input has a typeahead option which allows you to set the source:

$('input').tagsinput({
typeahead: {
source: ['Amsterdam', 'Washington', 'Sydney', 'Beijing', 'Cairo']
}
});

$('input').tagsinput({
typeahead: {
source: function(query) {
return $.get('http://someservice.com');
}
}
});
