常见的选择框控件：Selelct、FilteringSelect和ComboBox都是下拉框风格，而不是ListBox风格。
dojo还提供了一个dijit.form.MultiSelect控件可以解决问题并支持多选：http://dojotoolkit.org/reference-guide/1.10/dijit/form/MultiSelect.html
需要注意的是该空间不支持store这些，需要动态在JS代码中条件<OPTION>标签。
示例代码（在官网上的代码做了改动）
<!DOCTYPE html>
<html >
<head> <script>dojoConfig = {parseOnLoad: true}</script> <link rel="stylesheet" href="/lss/dojoroot/dijit/themes/claro/claro.css">
<script src="/lss/dojoroot/dojo/dojo.js" ></script> <script>
require([
"dijit/form/MultiSelect",
"dijit/form/Button",
"dojo/dom",
"dojo/_base/window",
"dojo/domReady!"],
function(MultiSelect, Button, dom, win){
var sel = dom.byId('dynamic');
var n = 0;
for(var i in dijit){
var c = win.doc.createElement('option');
c.innerHTML = i;
c.value = n++;
sel.appendChild(c);
} var myMultiSelect = new MultiSelect({ name: 'myMultiSelect' }, sel);
myMultiSelect.startup(); new Button({
onClick: function(){
alert(myMultiSelect.get('value'));
}
}, "progbutton").startup();
});
</script>
</head>
<body class="claro">
<select id="dynamic"></select>
<p><button id="progbutton" type="button">Get value</button></p>
