Kevin Brown 56dbbf8cdb Improve option generate speed
Now the options are mostly generated by hand before being passed
off to jQuery for templating. This fixes much of the speed issues
we had when they were entirely being generated through jQuery.

<p>
Select2 can take a regular select box like this...
</p>
<p>
<select class="js-states form-control"></select>
</p>
<p>
and turn it into this...
</p>
<p>
<select class="js-example-basic-single js-states form-control"></select>

<div class="col-md-8">

Select2 also supports multi-value select boxes. The select below is declared with the <code>multiple</code> attribute.

This works for multiple select boxes as well.

<h1>Loading array data</h1>
<p>
Select2 provides a way to load the data from a local array.
</p>
<p>
<select class="js-example-data-array form-control"></select>
</p>
<p>
You can provide initial selections with array data by providing the
option tag for the selected values, similar to how it would be done for
a standard select.
</p>
<p>
<select class="js-example-data-array-selected form-control">
<option value="2" selected="selected">duplicate</option>

<h1>Loading remote data</h1>
<p>
Select2 comes with AJAX support built in, using jQuery's AJAX methods.
</p>
<p>
<select class="js-example-data-ajax form-control"></select>
</p>
<pre data-fill-from=".js-code-data-ajax"></pre>
<p>
Select2 will pass any options in the <code>ajax</code> object to
jQuery's <code>$.ajax</code> function.
</p>

</script>
</div>
</section>
<section id="disabled-results" class="row">
<div class="col-md-4">
<h1>Disabled results</h1>
<p>
Select2 will correctly handled disabled results, both with data coming
from a standard select (when the <code>disabled</code> attribute is set)
and from remote sources, where the object has
<code>disabled: true</code> set.
</p>
<p>
<select class="js-example-disabled-results form-control">
<option value="one">First</option>
<option value="two" disabled="disabled">Second (disabled)</option>

<h1>Programmatic access</h1>
<p>
Select2 supports methods that allow programmatic control of the
component.
</p>
<p>
<button class="js-programmatic-open btn btn-success">
Open
</button>
<button class="js-programmatic-close btn btn-success">
Close
</button>

<script type="text/javascript" class="js-code-programmatic">
var $example = $(".js-example-programmatic");
$(".js-programmatic-open").on("click", function () { $example.select2("open"); });
$(".js-programmatic-close").on("click", function () { $example.select2("close"); });
</script>
</div>
</section>
<section id="tags" class="row">
<div class="col-md-4">
<h1>Tagging support</h1>
<p>
Select2 can be used to quickly set up fields used for tagging.
</p>
<p>
<select class="js-example-tags form-control">
<option value="one">First</option>
<option value="other">Other</option>
</select>
</p>
<p>
Note that when tagging is enabled the user can select from pre-existing
options or create a new tag by picking the first choice, which is what
the user has typed into the search box so far.
</p>

<div class="col-md-8">
<h2>Example code</h2>
<pre data-fill-from=".js-code-tags"></pre>
<script type="text/x-example-code" class="js-code-tags">
$(".js-example-tags").select2({
tags: true
})
</script>

<section id="matcher" class="row">
<div class="col-md-4">
<h1>Custom matcher</h1>
<p>
Unlike other dropdowns on this page, this one matches options only if
the term appears in the beginning of the string as opposed to anywhere:
</p>
<p>
<select class="js-example-matcher-start js-states form-control"></select>
</p>
<p>
This custom matcher uses a
<a href="compatibility.html">compatibility module</a> that is only
bundled in the
<a href="getting-started#versions">full version of Select2</a>. You also
have the option of using a
<a href="options.html#matcher">more complex matcher</a>.
</p>
</div>
<div class="col-md-8">
<h2>Example code</h2>
<pre data-fill-from=".js-code-matcher-start"></pre>

function matchStart (term, text) {
if (text.toUpperCase().indexOf(term.toUpperCase()) == 0) {

});
</script>
</div>

<section id="language" class="row">
<div class="col-md-4">
<h1>Multiple languages</h1>
<p>
Select2 supports displaying the messages in different languages, as well
as provding your own
<a href="options.html#language">custom messages</a>
that can be displayed.
</p>
<p>
<select class="js-example-language js-states form-control">
</select>
</p>
<p>
The language does not have to be defined when Select2 is being
initialized, but instead can be defined in the <code>[lang]</code>
attribute of any parent elements as <code>[lang="es"]</code>.
