    copied!<p>Here's a little sample to get you started: <a href="http://jsfiddle.net/eUDRV/3/" rel="nofollow noreferrer">http://jsfiddle.net/eUDRV/3/</a></p> <p>This example will move items (one or multiple) from the left to the right and back again. Whatever item(s) are selected in the right side will update the textbox on the right side.</p> <p>We are using the elements:</p> <ul> <li><code>select</code></li> <li><code>input type="button"</code></li> <li><code>input type="text"</code></li> </ul> <p>Framed by:</p> <ul> <li><code>div</code></li> <li><code>section</code></li> </ul> <p>Styled with simple CSS. Functionality is provided with JavaScript.</p> <p>I'm using the jQuery library to make things a little easier. This could also be done with pure JavaScript.</p> <p><div class="snippet" data-lang="js" data-hide="false" data-console="true" data-babel="false"> <div class="snippet-code"> <pre class="snippet-code-js lang-js prettyprint-override"><code>$("#btnLeft").click(function () { var selectedItem = $("#rightValues option:selected"); $("#leftValues").append(selectedItem); }); $("#btnRight").click(function () { var selectedItem = $("#leftValues option:selected"); $("#rightValues").append(selectedItem); }); $("#rightValues").change(function () { var selectedItem = $("#rightValues option:selected"); $("#txtRight").val(selectedItem.text()); });</code></pre> <pre class="snippet-code-css lang-css prettyprint-override"><code>SELECT, INPUT[type="text"] { width: 160px; box-sizing: border-box; } SECTION { padding: 8px; background-color: #f0f0f0; overflow: auto; } SECTION &gt; DIV { float: left; padding: 4px; } SECTION &gt; DIV + DIV { width: 40px; text-align: center; }</code></pre> <pre class="snippet-code-html lang-html prettyprint-override"><code>&lt;script src="https://ajax.googleapis.com/ajax/libs/jquery/1.9.1/jquery.min.js"&gt;&lt;/script&gt; &lt;section class="container"&gt; &lt;div&gt; &lt;select id="leftValues" size="5" multiple&gt;&lt;/select&gt; &lt;/div&gt; &lt;div&gt; &lt;input type="button" id="btnLeft" value="&amp;lt;&amp;lt;" /&gt; &lt;input type="button" id="btnRight" value="&amp;gt;&amp;gt;" /&gt; &lt;/div&gt; &lt;div&gt; &lt;select id="rightValues" size="4" multiple&gt; &lt;option&gt;1&lt;/option&gt; &lt;option&gt;2&lt;/option&gt; &lt;option&gt;3&lt;/option&gt; &lt;/select&gt; &lt;div&gt; &lt;input type="text" id="txtRight" /&gt; &lt;/div&gt; &lt;/div&gt; &lt;/section&gt;</code></pre> </div> </div> </p>
