Answer 1

It can be done something like this. Fiddle here

In example, a fixed width set on select and wrap a div with a lower width and overflow:hidden in order to mask/hide the dropdown. It has full support and essentially does hide the arrow in all browsers.

HTML

<div>
    <select>
        <option>one</option>
        <option>two</option>
        <option>three</option>
    </select>
</div>

CSS

div {
    width: 80px;
    overflow: hidden;
    border: 1px solid black;
}
select {
    width: 100px;
    border: 0px;
}

OR with pure CSS

select::-ms-expand {
    display: none;
}

OR with jQuery selectbox replacement.
It's a jQuery plugin.
