+        are using features not provided in the Select2 core. You can apply a
+        decorator to an adapter using the

+        You can also define nested configurations, which are typically needed for
+        options such as AJAX. Each level of nesting should be separated by two
+        dashes (<code>--</code>) instead of one. Due to
+        <a href="https://github.com/jquery/jquery/issues/2070">a jQuery bug</a>,

-      <p>
-        Select2 will automatically apply decorators to any adapters which have not

-        when you are using third-party adapters not provided by Select2, or you
-        are using features not provided in the Select2 core. You can apply a
-        decorator to an adapter using the
-        <code title="select2/utils">Utils.Decorate</code> method provided with
-        Select2.

-        All core options that use decorators or adapters will clearly state it

-        note what adapter is given.

-        Declaring configuration in the <code>data-*</code> attributes
-      </h2>
-
-      <p>
-        It is recommended that you declare your configuration options for Select2
-        when initializing Select2. You can also define your configuration options
-        by using the HTML5 <code>data-*</code> attributes, which will override
-        any options set when initializing Select2 and any defaults.
-      </p>
-
-      <p>
-        This means that if you declare your <code>&lt;select&gt;</code> tag as...
-      </p>
-
-<pre class="prettyprint">
-&lt;select data-tags="true" data-placeholder="Select an option"&gt;&lt;/select&gt;
-</pre>
-
-      <p>
-        Will be interpreted the same as initializing Select2 as...
-      </p>
-
-<pre class="prettyprint linenums">
-$("select").select2({
-  tags: "true",
-  placeholder: "Select an option"
-});
-</pre>
-
-      <p>
-        You can also define nested configurations, which are typically needed for
-        options such as AJAX. Each level of nesting should be separated by two
-        dashes (<code>--</code>) instead of one. Due to
-        <a href="https://github.com/jquery/jquery/issues/2070">a jQuery bug</a>,
-        nested options using <code>data-*</code> attributes
-        <a href="https://github.com/select2/select2/issues/2969">do not work in jQuery 1.x</a>.
-      </p>
-
-<pre class="prettyprint">
-&lt;select data-ajax--url="http://example.org/api/test" data-ajax--cache="true"&gt;&lt;/select&gt;
-</pre>
-
-      <p>
-        Which will be interpreted the same as initializing Select2 with...
-      </p>
-
-<pre class="prettyprint linenums">
-$("select").select2({
-  ajax: {
-    url: "http://example.org/api/test",
-    cache: "true"

-
-      <p>
-        The value of the option is subject to jQuery's

-        HTML5 data attributes.

-        <a href="announcements-4.0.html#builds">viewing the 4.0 release notes</a>.
-        Select2 automatically loads some modules when the adapters are being
-        automatically constructed, so those who are using Select2 with a custom
-        AMD build using their own system may need to specify the paths that are
-        generated to the Select2 modules.
