可以创建一个div来充当下拉菜单吗？

Question

I am using jquery to populate a dropdown menu from a text file and it is working fine. But visually, I would like it to look different.

My dropdown is in a div. What I would like to do is make the div itself clickable so that when you click it, the dropdown menu options pop up. And when an option is selected, the div's label is set to the text of the selected option.

Is there someway to make the dropdown menu hidden but still functional?

    });
});

Here take a look: http://jsfiddle.net/4Zw32/

Basically you can select which div is selected by searching for div with class selected and you could assign data attribute to get additional value.

Css

* { margin: 0;  padding: 0; }

.sel {
    color:white;
    width: 250px;
    min-height: 40px;
    box-sizing: border-box;
    background-color: #55E6FA;
    overflow: hidden;
}
.txt { padding: 10px; }
.selected { background-color: #31A9B9; }
.hide { display: none; }
.sel .options div:hover { background-color: #31A9B9; }

.sel .options {
    width: 250px;
    background-color: #66f7FB;
}
.sel .options div {
    transition: all 0.2s ease-out;
    padding: 10px;
}

Jquery

var sel = $('.sel'),
    txt = $('.txt'),
    options = $('.options');

sel.click(function (e) {
    e.stopPropagation();
    options.show();
});

$('body').click(function (e) {
    options.hide();
});

options.children('div').click(function (e) {
    e.stopPropagation();
    txt.text($(this).text());
    $(this).addClass('selected').siblings('div').removeClass('selected');
    options.hide();
});
