Does anyone have a solution for styling the borders of "select" elements in Internet Explorer using CSS?
As far as I know, it's not possible in IE because it uses the OS component.
Here is a link where the control is replaced, but I don't know if thats what you want to do.
<select>
Something New, Part 1So you've built a beautiful, standards-compliant site utilizing the latest and
greatest CSS techniques. You've mastered control of styling every element, but
in the back of your mind, a little voice is nagging you about how ugly your
<select>
s are. Well, today we're going to explore a way to silence that
little voice and truly complete our designs. With a little DOM scripting and
some creative CSS, you too can make your <select>
s beautiful… and you won't
have to sacrifice accessibility, usability or graceful degradation.
We all know the <select>
is just plain ugly. In fact, many try to limit its
use to avoid its classic web circa 1994 inset borders. We should not avoid
using the <select>
though--it is an important part of the current form
toolset; we should embrace it. That said, some creative thinking can improve
it.
<select>
We'll use a simple for our example:
<select id="something" name="something">
<option value="1">This is option 1</option>
<option value="2">This is option 2</option>
<option value="3">This is option 3</option>
<option value="4">This is option 4</option>
<option value="5">This is option 5</option>
</select>
[Note: It is implied that this <select>
is in the context of a complete
form.]
So we have five <option>
s within a <select>
. This <select>
has a
uniquely assigned id
of "something." Depending on the browser/platform
you're viewing it on, your <select>
likely looks roughly like this:

or this

Let's say we want to make it look a little more modern, perhaps like this:
(source: easy-designs.net)
So how do we do it? Keeping the basic <select>
is not an option. Apart from
basic background color, font and color adjustments, you don't really have a
lot of control over the .
However, we can mimic the superb functionality of a <select>
in a new form
control without sacrificing semantics, usability or accessibility. In order to
do that, we need to examine the nature of a <select>
.
A <select>
is, essentially, an unordered list of choices in which you can
choose a single value to submit along with the rest of a form. So, in essence,
it's a <ul>
on steroids. Continuing with that line of thinking, we can
replace the <select>
with an unordered list, as long as we give it some
enhanced functionality. As <ul>
s can be styled in a myriad of different
ways, we're almost home free. Now the questions becomes "how to ensure that we
maintain the functionality of the <select>
when using a <ul>
?" In other
words, how do we submit the correct value along with the form, if we
are no longer using a form control?
Enter the DOM. The final step in the process is making the <ul>
function/feel like a <select>
, and we can accomplish that with
JavaScript/ECMA Script and a little clever CSS. Here is the basic list of
requirements we need to have a functional faux <select>
:
With this plan, we can begin to tackle each part in succession.
So first we need to collect all of the attributes and s out of the and rebuild it as a . We accomplish this by running the following JS:
function selectReplacement(obj) {
var ul = document.createElement('ul');
ul.className = 'selectReplacement';
// collect our object's options
var opts = obj.options;
// iterate through them, creating <li>s
for (var i=0; i<opts.length; i++) {
var li = document.createElement('li');
var txt = document.createTextNode(opts[i].text);
li.appendChild(txt);
ul.appendChild(li);
}
// add the ul to the form
obj.parentNode.appendChild(ul);
}
You might be thinking "now what happens if there is a selected <option>
already?" We can account for this by adding another loop before we create the
<li>
s to look for the selected <option>
, and then store that value in
order to class
our selected <li>
as "selected":
…
var opts = obj.options;
// check for the selected option (default to the first option)
for (var i=0; i<opts.length; i++) {
var selectedOpt;
if (opts[i].selected) {
selectedOpt = i;
break; // we found the selected option, leave the loop
} else {
selectedOpt = 0;
}
}
for (var i=0; i<opts.length; i++) {
var li = document.createElement('li');
var txt = document.createTextNode(opts[i].text);
li.appendChild(txt);
if (i == selectedOpt) {
li.className = 'selected';
}
ul.appendChild(li);
…
[Note: From here on out, option 5 will be selected, to demonstrate this functionality.]
Now, we can run this function on every <select>
on the page (in our case,
one) with the following:
function setForm() {
var s = document.getElementsByTagName('select');
for (var i=0; i<s.length; i++) {
selectReplacement(s[i]);
}
}
window.onload = function() {
setForm();
}
We are nearly there; let's add some style.
I don't know about you, but I am a huge fan of CSS dropdowns (especially the
Suckerfish variety). I've been
working with them for some time now and it finally dawned on me that a
<select>
is pretty much like a dropdown menu, albeit with a little more
going on under the hood. Why not apply the same stylistic theory to our
faux-<select>
? The basic style goes something like this:
ul.selectReplacement {
margin: 0;
padding: 0;
height: 1.65em;
width: 300px;
}
ul.selectReplacement li {
background: #cf5a5a;
color: #fff;
cursor: pointer;
display: none;
font-size: 11px;
line-height: 1.7em;
list-style: none;
margin: 0;
padding: 1px 12px;
width: 276px;
}
ul.selectOpen li {
display: block;
}
ul.selectOpen li:hover {
background: #9e0000;
color: #fff;
}
Now, to handle the "selected" list item, we need to get a little craftier:
ul.selectOpen li {
display: block;
}
ul.selectReplacement li.selected {
color: #fff;
display: block;
}
ul.selectOpen li.selected {
background: #9e0000;
display: block;
}
ul.selectOpen li:hover,
ul.selectOpen li.selected:hover {
background: #9e0000;
color: #fff;
}
Notice that we are not using the :hover pseudo-class for the <ul>
to make it
open, instead we are class
-ing it as "selectOpen". The reason for this is
two-fold:
<select>
behave like a real <select>
, we need the list to open in an onclick
event and not on a simple mouse-over.To implement this, we can take what we learned from Suckerfish and apply it to
our own JavaScript by dynamically assigning and removing this class
in
``onclickevents for the list items. To do this right, we will need the
ability to change the
onclick` events for each list item on the fly to switch
between the following two actions:
<select>
when clicking the selected/default option when the list is collapsed; and<select>
.We will create a function called selectMe()
to handle the reassignment of
the "selected" class
, reassignment of the onclick
events for the list
items, and the collapsing of the faux-<select>
:
As the original Suckerfish taught us, IE will not recognize a hover state on
anything apart from an <a>
, so we need to account for that by augmenting
some of our code with what we learned from them. We can attach onmouseover and
onmouseout events to the "selectReplacement" class
-ed <ul>
and its
<li>
s:
function selectReplacement(obj) {
…
// create list for styling
var ul = document.createElement('ul');
ul.className = 'selectReplacement';
if (window.attachEvent) {
ul.onmouseover = function() {
ul.className += ' selHover';
}
ul.onmouseout = function() {
ul.className =
ul.className.replace(new RegExp(" selHover\\b"), '');
}
}
…
for (var i=0; i<opts.length; i++) {
…
if (i == selectedOpt) {
li.className = 'selected';
}
if (window.attachEvent) {
li.onmouseover = function() {
this.className += ' selHover';
}
li.onmouseout = function() {
this.className =
this.className.replace(new RegExp(" selHover\\b"), '');
}
}
ul.appendChild(li);
}
Then, we can modify a few selectors in the CSS, to handle the hover for IE:
ul.selectReplacement:hover li,
ul.selectOpen li {
display: block;
}
ul.selectReplacement li.selected {
color: #fff;
display: block;
}
ul.selectReplacement:hover li.selected**,
ul.selectOpen li.selected** {
background: #9e0000;
display: block;
}
ul.selectReplacement li:hover,
ul.selectReplacement li.selectOpen,
ul.selectReplacement li.selected:hover {
background: #9e0000;
color: #fff;
cursor: pointer;
}
Now we have a list behaving like a <select>
; but we still
need a means of changing the selected list item and updating the value of the
associated form element.
We already have a "selected" class
we can apply to our selected list item,
but we need a way to go about applying it to a <li>
when it is clicked on
and removing it from any of its previously "selected" siblings. Here's the JS
to accomplish this:
function selectMe(obj) {
// get the <li>'s siblings
var lis = obj.parentNode.getElementsByTagName('li');
// loop through
for (var i=0; i<lis.length; i++) {
// not the selected <li>, remove selected class
if (lis[i] != obj) {
lis[i].className='';
} else { // our selected <li>, add selected class
lis[i].className='selected';
}
}
}
[Note: we can use simple className
assignment and emptying because we are in
complete control of the <li>
s. If you (for some reason) needed to assign
additional classes to your list items, I recommend modifying the code to
append and remove the "selected" class to your className
property.]
Finally, we add a little function to set the value of the original <select>
(which will be submitted along with the form) when an <li>
is clicked:
function setVal(objID, selIndex) {
var obj = document.getElementById(objID);
obj.selectedIndex = selIndex;
}
We can then add these functions to the onclick
event of our <li>
s:
…
for (var i=0; i<opts.length; i++) {
var li = document.createElement('li');
var txt = document.createTextNode(opts[i].text);
li.appendChild(txt);
li.selIndex = opts[i].index;
li.selectID = obj.id;
li.onclick = function() {
setVal(this.selectID, this.selIndex);
selectMe(this);
}
if (i == selectedOpt) {
li.className = 'selected';
}
ul.appendChild(li);
}
…
There you have it. We have created our functional faux-. As we have
not hidden the original
yet, we can [watch how it
behaves](files/4.html) as we choose different options from our
faux-
. Of course, in the final version, we don't want the original
to show, so we can hide it by
class`-ing it as "replaced," adding
that to the JS here:
function selectReplacement(obj) {
// append a class to the select
obj.className += ' replaced';
// create list for styling
var ul = document.createElement('ul');
…
Then, add a new CSS rule to hide the
select.replaced {
display: none;
}
With the application of a few images to finalize the design (link not available) , we are good to go!
