The issue here is, when I specify require it does not act properly because the first field is selected.. it ends up producing NULL instead of actually requiring user to enter a choice...
Anything I can do to fix this?
It is because you have to make the first option value the empty string. You will have to come with another value for your "none" option.

This is pure HTML.

<label for="select-choice">Birthday:</label>

<option value="0" selected disabled>Month</option>
<option value="january">Jan</option>

<option value="2012">2012</option>
<option value="2011">2011</option>
The Sign Up or Register page is okay but I could not validate the birthday, When I try filling it on a browser I expect it to demand or require birthday option, every other input option was demanding or requiring me to input an information but if I purposely did not fill the birthday and hit the submit button it will go through just like that, please how do I validate the birthday using HTML?
You just need to add "required" to each of your selects and then just add an empty value instead of a "0" value. When you press a button, it will detect it has no value and will automatically make the select required.

Does anyone know why a form field name would cause Chrome's autofill to stop working correctly? If you open the fiddle I've created in Chrome, you'll notice the Card Number field populates correctly, but not the expiry month and year. If you change the name of the BirthDate.MM select list to BirthDate.Foo and BirthDate.YYYY to BirthDate.Bar; and then and re-run, the credit card autofill works as expected. Now, an obvious suggestion would be to simply disable the bday- autofill and change the those values to "off" or completely remove the autocomplete attribute. Astoundingly, removing the autocomplete attribute or changing the bday- values to "off" on those fields then breaks the address autofill!!!
The solution to the autofill problem itself is simply change the field names. What I want to know is why? Can anyone clarify how I unwittingly poked Chrome's field name sniffing feature?
<fieldset>

<div><input autocomplete="cc-number" id="CreditCard_CardNumber" maxlength="16" name="CreditCard.CardNumber" pattern="\d*" required="" type="text" placeholder="Card Number" value="" /></div>

Use the lower-case version of your names.
For me , using Name as name attribute is not working, autofill recognizes the field as CC !!
If I change it to name , works like a charm.
Hope this helps!
This is my simple HTML Select Program ,
by default its showing value as Volvo (the first value )
Is it possible that , not to show any value and let the user select ??
<!DOCTYPE html>
<html>
<body>
<form action="demo_form.asp">
<select name="cars">
<option value="volvo">Volvo</option>
<option value="saab">Saab</option>
<option value="opel">Opel</option>
<option value="audi">Audi</option>
</select>
<input type="submit">
</form>

It's really simple. Just add a blank option:
<form action="demo_form.asp">
<select name="cars">
<option></option>
<option value="volvo">Volvo</option>
<option value="saab">Saab</option>
<option value="opel">Opel</option>
<option value="audi">Audi</option>
</select>
<input type="submit">
</form>
Add a blank option to the first position. Be sure to give it a value that you can then check for in your submit handler. EDIT: Or just use selectedIndex.
i.e.
if(document.getElementById("select1").selectedIndex != 0){
form1.submit();
}
else {alert("Please select a value!");}
to validate they have selected something.
<form name="form1" id="form1" action="demo_form.asp">
<select id="select1"name="cars">
<option value="none"></option>
<option value="volvo">Volvo</option>
<option value="saab">Saab</option>
<option value="opel">Opel</option>
<option value="audi">Audi</option>
</select>
<input type="submit">
</form>
There are two ways:
1) Disable first item:
<select name="cars">
<option value="" disabled>[Select an item]</option>
<option value="volvo">Volvo</option>
<option value="saab">Saab</option>
<option value="opel">Opel</option>
<option value="audi">Audi</option>
</select>
2) Make first item empty, as already suggested.
<select name="cars">
<option value=""></option>
<option value="volvo">Volvo</option>
<option value="saab">Saab</option>
<option value="opel">Opel</option>
<option value="audi">Audi</option>
</select>
create a div (i called it "noShow"),
<div class="noShow">
<form action="demo_form.asp">
<select name="cars">
<option value="volvo">Volvo</option>
<option value="saab">Saab</option>
<option value="opel">Opel</option>
<option value="audi">Audi</option>
</select>
<input type="submit">
</form>
</div> <!-- end noShow DIV
then, using Style sheets (CSS), apply this to the cars
.noShow option:first-child{
display:none;
try that, good luck
There's no "clean" way to do what you are asking - an HTML select will always display one of the values.
You can, however, include a 'Not Selected' option:
<option value=''>--Not Selected--</option>
but then you also have to do some validation to make sure that the user actually picks a valid value. That's a topic for a different question. :)
Easiest way is to do something like this, if you also wanna provide some information:
<form action="demo_form.asp">
<select name="cars">
<option value="default">Pick Something!</option>
<option value="volvo">Volvo</option>
<option value="saab">Saab</option>
<option value="opel">Opel</option>
<option value="audi">Audi</option>
</select>
<input type="submit">
</form>
Is it possible to set a default prompt when nothing is selected for select box using css? or is there an elegant way to deal with this other than
<option>Select Here</option>?
Try this:
<select>
<option value="" disabled>Select one--</option>
<option value="someVal1">Option 1</option>
<option value="someVal2">Option 2</option>
<option value="someVal3">Option 3</option>
<option value="someVal4">Option 4</option>
</select>
The accepted answer did not work for me as expected.
If you need the "Select one option" to be the selected one by default , this worked for me
<select id="selected_option" name="selected_option">
<option value="default" selected="selected">Select one option </option>
<option value="someVal1">Option 1</option>
<option value="someVal2">Option 2</option>
<option value="someVal3">Option 3</option>
<option value="someVal4">Option 4</option>
</select>
Is also important that the select has id and name so when you submit the form the value will be part of the POST or GET
<select>
<option style="display:none">Empty</option>
<option>button1</option>
<option>button2</option>
</select>
This is how I use for setup the default prompt but it will not set a default value. It use a HTML5 validation required. It may be a little bit shift from the question but I hope it could help as alternative.
<select id="car" name="car[brand]" required>
<option disabled selected>Select Car Brand</option>
<option value="volvo">Volvo</option>
<option value="saab">Saab</option>
<option value="opel">Opel</option>
<option value="audi">Audi</option>
</select>
Try using option with unset value
<select>
<option value>Select something</option>
<option value="1">Foo</option>
<option value="2">Bar</option>
</select>
i see there is a disabled property on a specific item in the dropdown list but is there an enabled property on the whole html dropdown itself?
any suggestions?
According to the HTML 4 spec a select element has a disabled attribute.
So
<select disabled>
<option>Something</option>
</select>
should work
disabled="disabled"
This will disable a value within the combo box (it will still show up, but it will not have the ability to be selected):
<select>
<option disabled="disabled" value="volvo">Volvo</option>
<option value="saab">Saab</option>
<option value="mercedes">Mercedes</option>
<option value="audi">Audi</option>
</select>
This will disable the whole combo box:
<select disabled="disabled">
<option value="volvo">Volvo</option>
<option value="saab">Saab</option>
<option value="mercedes">Mercedes</option>
<option value="audi">Audi</option>
</select>
may this will help
is same as :
<html>
<head>
<script type="text/javascript">
function makeDisable(){
var x=document.getElementById("mySelect")
x.disabled=true
}
function makeEnable(){
var x=document.getElementById("mySelect")
x.disabled=false
}</script></head><body><form>
<select id="mySelect"><option>Apple</option><option>Banana</option>
<option>Orange</option>
</select>
<input type="button" onclick="makeDisable()" value="Disable list">
<input type="button" onclick="makeEnable()" value="Enable list">
</form>
</body>
</html>
