Nope, not possible. Or not valid at least.
不，不可能。或者至少无效。

No. To achieve that you can try this: Use a div to show the selected item and put a div or a button inside it like a drop-down button. When the button is clicked it shows another div containing all your options.
不。要实现这一点，您可以尝试以下操作：使用 div 显示所选项目，并在其中放置一个 div 或按钮（如下拉按钮）。单击按钮时，它会显示另一个包含所有选项的 div。
A little bit complex so not necessary to achieve that effect just to make it look pretty
有点复杂所以没有必要为了让它看起来漂亮而达到那个效果

You can replace your Options with JS plugin:
你可以用 JS 插件替换你的选项：
HTML:
HTML：
<h3>multiSelect = false</h3>
<div id="combo1" class="combo"></div><br>
<button id="get1">get1</button>
<button id="set1">set1</button>
JS:
JS：
$(function(){
var dd = [];
for(var i=1;i<=4; i++)
dd.push({ code: i + '', name: 'Employee ' + i });
var cfg = {
keyField: 'code',
displayField: 'name',
multiSelect: false,
width: 200,
boxWidth: 200,
cols : [{
field: 'code', width: '30%'
},{
field: 'name', width: '70%'
}],
data: dd
};
var cfg1 = $.extend({}, cfg);
var cb1 = $('#combo1').mac('combo', cfg1);
$('#get1').click(function(){
alert(cb1.selected);
});
$('#set1').click(function(){
cb1.select(2);
});
});
});
