Select2 uses the <code>placeholder</code> attribute on multiple select

<h1>Loading array data</h1>

Select2 provides a way to load the data from a local array.

<select class="js-example-data-array form-control"></select>

You can provide initial selections with array data by providing the

a standard select.

<h1>Loading remote data</h1>
|
|
|
|
<p>
|
|
Select2 comes with AJAX support built in, using jQuery's AJAX methods.
|
|
In this example, we can search for repositories using GitHub's API.
|
|
</p>
|
|
|
|
<p>
|
|
<select class="js-example-data-ajax form-control">
|

<option value="select2/select2" selected="selected">select2/select2</option>
|
|
</select>
|
|
</p>
|
|
|
|
<p>
|
|
When using Select2 with remote data, the HTML required for the
|
|
<code>select</code> is the same as any other Select2. If you need to
|
|
provide default selections, you just need to include an
|
|
<code>option</code> for each selection that contains the value and text
|
|
that should be displayed.
|
|
</p>
|
|
|
|
<pre data-fill-from=".js-code-data-ajax-html"></pre>
|
|
|
|
<p>
|
|
You can configure how Select2 searches for remote data using the
|
|
<code>ajax</code> option. More information on the individual options
|
|
that Select2 handles can be found in the
|
|
<a href="options.html#ajax">options documentation for <code>ajax</code></a>.

|
</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, or the <code>transport</code>
|
|
function you specify.
|
|

|
