<h2 id="data-adapters-select-tag">
Can Select2 be used with a <code><select></code> tag?
</h2>
<h3>
Does Select2 support nesting options?
</h3>
<p>
Yes, just like in a standard <code>select</code>.
</p>
<h3>
How many levels of nesting can there be?
</h3>
<p>
Only a single level of nesting is allowed per the HTML specification.
</p>
<h3>
Can <code><optgroup></code> tags be made selectable?
</h3>
<p>
No. This is a limitation of the HTML specification and is not a limitation that Select2 can overcome.
</p>
<h3>
How are <code><option></code> and <code><optgroup></code> tags serialized into data objects?
</h3>
<p>
Select2 will convert the <code><option></code> tag into a data object based on the following rules.
</p>
<pre class="prettyprint linenums">
{
"id": "value attribute" || "option text",
"text": "label attribute" || "option text",
"element": HTMLOptionElement
}
</pre>
<p>
And <code><optgroup></code> tags will be converted into data objects using the following rules
</p>
<pre class="prettyprint linenums">
{
"text": "label attribute",
"children": [ option data object, ... ],
"elment": HTMLOptGroupElement
}
</pre>
