+
+<p>The <strong>read-only</strong> {{domxref("HTMLSelectElement")}} property <code><strong>selectedOptions</strong></code> contains a list of the {{HTMLElement("option")}} elements contained within the {{HTMLElement("select")}} element that are currently selected. The list of selected options is an {{domxref("HTMLCollection")}} object with one entry per currently selected option.</p>
+
+<p>An option is considered selected if it has an {{domxref("HTMLOptionElement.selected")}} attribute.</p>
+
+<h2 id="Syntax">Syntax</h2>
+
+<pre class="syntaxbox">var <em>selectedCollection</em> = <em>HTMLSelectElement</em>.selectedOptions;</pre>
+
+<h3 id="Value">Value</h3>
+
+<p>An {{domxref("HTMLCollection")}} which lists every currently selected {{domxref("HTMLOptionElement")}} which is either a child of the {{domxref("HTMLSelectElement")}} or of an {{domxref("HTMLOptGroupElement")}} within the <code>&lt;select&gt;</code> element.</p>
+
+<p>In other words, any option contained within the <code>&lt;select&gt;</code> element may be part of the results, but option groups are not included in the list.</p>
+
+<p>If no options are currently selected, the collection is empty and returns a {{domxref("HTMLCollection.length", "length")}} of 0.</p>
+
+<h2 id="Example">Example</h2>
+
+<p>In this example, a {{HTMLElement("select")}} element with a number of options is used to let the user order various food items.</p>
+
+<h3 id="HTML">HTML</h3>
+
+<p>The HTML that creates the selection box and the {{HTMLElement("option")}} elements representing each of the food choices looks like this:</p>
+
+<pre class="brush: html">&lt;label for="foods"&gt;What do you want to eat?&lt;/label&gt;&lt;br&gt;
+&lt;select id="foods" name="foods" size="7" multiple&gt;
+ &lt;option value="1"&gt;Burrito&lt;/option&gt;
+ &lt;option value="2"&gt;Cheeseburger&lt;/option&gt;
+ &lt;option value="3"&gt;Double Bacon Burger Supreme&lt;/option&gt;
+ &lt;option value="4"&gt;Pepperoni Pizza&lt;/option&gt;
+ &lt;option value="5"&gt;Taco&lt;/option&gt;
+&lt;/select&gt;
+&lt;br&gt;
+&lt;button name="order" id="order"&gt;
+ Order Now
+&lt;/button&gt;
+&lt;p id="output"&gt;
+&lt;/p&gt;</pre>
+
+<p>The <code>&lt;select&gt;</code> element is set to allow multiple items to be selected, and it is 7 rows tall. Note also the {{HTMLElement("button")}}, whose role it is to trigger fetching the {{domxref("HTMLCollection")}} of selected elements using the <code>selected</code> property.</p>
+
+<h3 id="JavaScript">JavaScript</h3>
+
+<p>The JavaScript code that establishes the event handler for the button, as well as the event handler itself, looks like this:</p>
+
+<pre class="brush: js">let orderButton = document.getElementById("order");
+let itemList = document.getElementById("foods");
+let outputBox = document.getElementById("output");
+
+orderButton.addEventListener("click", function() {
+ let collection = itemList.selectedOptions;
+ let output = "";
+
+ for (let i=0; i&lt;collection.length; i++) {
+ if (output === "") {
+ output = "Your order for the following items has been placed: ";
+ }
+ output += collection[i].label;
+
+ if (i === (collection.length - 2) &amp;&amp; (collection.length &lt; 3)) {
+ output += " and ";
+ } else if (i &lt; (collection.length - 2)) {
+ output += ", ";
+ } else if (i === (collection.length - 2)) {
+ output += ", and ";
+ }
+ }
+
+ if (output === "") {
+ output = "You didn't order anything!";
+ }
+
+ outputBox.innerHTML = output;
+}, false);</pre>
+
+<p>This script sets up a {{event("click")}} event listener on the "Order Now" button. When clicked, the event handler fetches the list of selected options using <code>selectedOptions</code>, then iterates over the options in the list. A string is constructed to list the ordered items, with logic to build the list using proper English grammar rules (including a {{interwiki("wikipedia", "serial comma")}}).</p>
+
+<h3 id="Result">Result</h3>
+
+<p>The resulting content looks like this in action:</p>
+
+<p>{{EmbedLiveSample("Example", 600, 250)}}</p>
