I have a select drop down in which there are some options and optgroup. I dont want to use the label of optgroup. If i set it to empty or not mention as an attribute of optgroup, i just see a space between optgroup and option element. Is there any way to remove it? Here is a jsfiddle for it.
<select>
<option>Category 1</option>
<optgroup>
<option>a</option>
<option>b</option>
</optgroup>
<option>Category 2</option>
<optgroup>
<option>c</option>
<option>d</option>
</optgroup>
</select>
I want to remove the space between 'Category 1' and 'a', 'Category 2' and 'c'.
Note: I use the random names for drop-down list, they are different in my project, user can select the category as well. If we make category as label then we cant select it further. So the solution should be in changing css or something like this
Actually you are setting group heading in <option> tag. so you have to change your code like below :
<select>
<optgroup label="Category 1">
<option>a</option>
<option>b</option>
</optgroup>
<optgroup label="Category 2">
<option>c</option>
<option>d</option>
</optgroup>
</select>
And if you want to style this according to you, you should use some select plugins based on jquery
Chosen : Chosen plugin
Bootstrap Select : Bootstrap Select Plugin
If you wish to be able to select a category as well, I would advise the following:
<select>
<option>-- please select --
<optgroup label="Category 1">
<option>All
<option>a
<option>b
<optgroup label="Category 2">
<option>All
<option>c
<option>d
</select>
Add this to your stylesheet , Here we are forcefully updating the SumoSelect CSS , If you have no use of labels . This is apt .
.SumoSelect > .optWrapper > .options li.group > label{padding: 0px 0px !important;}
You can also consider a dumb solution like this. It's upsides are - it's simple and it works. The downsides are: some people may call it a bad practice and it doesn't involve optgroups if you absolutely need them for some reason.
<select>
<option>Category 1</option>
<option> a</option>
<option> b</option>
<option>Category 2</option>
<option> a</option>
<option> b</option>
</select>
I have a very weird requirement, wherein I am required to have no option selected by default in drop down menu in HTML. However,
I cannot use this,
<select>
<option></option>
<option>Option 1</option>
<option>Option 2</option>
<option>Option 3</option>
</select>
Because, for this I will have to do validation to handle the first option. Can anyone help me in achieving this target without actually including the first option as part of the select tag?
Maybe this will be helpful
<select>
<option disabled selected value> -- select an option -- </option>
<option>Option 1</option>
<option>Option 2</option>
<option>Option 3</option>
</select>
-- select an option -- Will be displayed by default. But if you choose an option, you will not be able to select it back.
You can also hide it using by adding an empty option
<option style="display:none">
so it won't show up in the list anymore.
Option 2
If you don't want to write CSS and expect the same behaviour of the solution above, just use:
<option hidden disabled selected value> -- select an option -- </option>
You could use Javascript to achieve this. Try the following code:
HTML
<select id="myDropdown">
<option>Option 1</option>
<option>Option 2</option>
<option>Option 3</option>
</select>
JS
document.getElementById("myDropdown").selectedIndex = -1;
or JQuery
$("#myDropdown").prop("selectedIndex", -1);
Today (2015-02-25)
This is valid HTML5 and sends a blank (not a space) to the server:
<option label=" "></option>
Verified validity on http://validator.w3.org/check
Verified behavior with Win7(IE11 IE10 IE9 IE8 FF35 Safari5.1) Ubuntu14.10(Chrome40, FF35) OSX_Yosemite(Safari8, Chrome40) Android(Samsung-Galaxy-S5)
The following also passes validation today, but passes some sort of space character to the server from most browsers (probably not desirable) and a blank on others (Chrome40/Linux passes a blank):
<option> </option>
Previously (2013-08-02)
According to my notes, the non-breaking-space entity inside the option tags shown above produced the following error in 2013:
Error: W3C Markup Validaton Service (Public): The first child option
element of a select element with a required attribute and without a
multiple attribute, and whose size is 1, must have either an empty
value attribute, or must have no text content.
At that time, a regular space was valid XHTML4 and sent a blank (not a space) to the server from every browser:
<option> </option>
Future
It would make my heart glad if the spec was updated to explicitly allow a blank option. Preferably using the briefest syntax. Either of the following would be great:
<option />
<option></option>
Test File
<!DOCTYPE html>
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=UTF-8" />
<title>Test</title>
</head>
<body>
<form action="index.html" method="post">
<select name="sel">
<option label=" "></option>
</select>
</form>
</body>
</html>
<td><b>Field Label:</b><br>
<select style='align:left; width:100%;' id='some_id' name='some_name'>
<option hidden selected>Select one...</option>
<option value='Value1'>OptLabel1</option>
<option value='Value2'>OptLabel2</option>
<option value='Value3'>OptLabel3</option></select>
</td>
Just put "hidden" on option you want to hide on dropdown list.
Solution that works by only using CSS:
A: Inline CSS
<select>
<option style="display:none;"></option>
<option>Option 1</option>
<option>Option 2</option>
<option>Option 3</option>
</select>
B: CSS Style Sheet
If you have a CSS file at hand, you can target the first option using:
select.first-opt-hidden option:first-of-type {
display:none;
}
<select class="first-opt-hidden">
<option></option>
<option>Option 1</option>
<option>Option 2</option>
<option>Option 3</option>
</select>
This should help:
https://www.w3schools.com/tags/att_select_required.asp
<form>
<select required>
<option value="">None</option>
<option value="volvo">Volvo</option>
<option value="saab">Saab</option>
<option value="mercedes">Mercedes</option>
<option value="audi">Audi</option>
</select>
<button type="submit">Submit</button>
</form>
Just a small remark:
some Safari browsers do not seem to respect neither the "hidden" attribute nor the style setting "display:none" (tested with Safari 12.1 under MacOS 10.12.6). Without an explicit placeholder text, these browsers simply show an empty first line in the list of options. It may therefore be useful to always provide some explanatory text for this "dummy" entry:
<option hidden disabled selected value>(select an option)</option>
Thanks to the "disabled" attribute, it won't be actively selected anyway.
<select required>
<option value="" disabled selected>None</option>
<option value="volvo">Volvo</option>
<option value="saab">Saab</option>
<option value="mercedes">Mercedes</option>
<option value="audi">Audi</option>
</select>
You can avoid custom validation in this case.
I understand what you are trying to do.The best and the most successful way is :
<select name='department' required>
<option value="">None</option>
<option value="Teaching">Teaching department</option>
<option value="nonTeaching">Non-teaching department</option>
</select>
I found it really interesting because I just experienced the same thing not so long time ago.
However, I came across to an example on the Internet about the solution regarding this.
Without any further ado, see the code fragment below:
<select>
<option value data-isdefault="true">--Choose one Option--</option>
<option>Option 1</option>
<option>Option 2</option>
<option>Option 3</option>
</select>
With that, it will stay un-submittable but selectable, anytime. More convenience for User Interface and great for User Experience.
Well that's all, I hope it helps. Cheers!
There is no HTML solution. By the HTML 4.01 spec, browser behavior is undefined if none of the option elements has the selected attribute, and what browsers do in practice is that they make the first option pre-selected.
As a workaround, you could replace the select element by a set of input type=radio elements (with the same name attribute). This creates a control of the same kind though with different appearance and user interface. If none of the input type=radio elements has the checked attribute, none of them is initially selected in most modern browsers.
I'm using Laravel 5 framework and #Gambi `s answer worked for me as well but with some changes for my project.
I have the option values in a database table and I use them with a foreach statement. But before the statement I have added an option with #Gambit suggested settings and it worked.
Here my exemple:
#isset($keys)
<select>
<option disabled selected value></option>
#foreach($keys as $key)
<option>{{$key->value)</option>
#endforeach
</select>
#endisset
I hope this helps someone as well. Keep up the good work!
Try this:
<h2>Favorite color</h2>
<select name="color">
<option value=""></option>
<option>Pink</option>
<option>Red</option>
<option>Blue</option>
</select>
The first option in the drop down would be blank.
In order to show please select a value in drop down and hide it after some value is selected . please use the below code.
it will also support required validation.
<select class="form-control" required>
<option disabled selected value style="display:none;">--Please select a value</option>
<option >Data 1</option>
<option >Data 2</option>
<option >Data 3</option>
</select>
If you are using Angular (2+), (or any other framework), you could add some logic. The logic would be: only display an empty option if the user did not select any other yet.
So after the user selected an option, the empty option disappears.
For Angular (9) this would look something like this:
<select>
<option *ngIf="(hasOptionSelected$ | async) === false"></option>
<option *ngFor="let option of (options$ | async)[value]="option.id">{{ option.title }}</option>
</select>
For those who are using <select multiple> (combobox; no dropdown), this worked for me:
<select size=1 disabled multiple>
<option hidden selected></option>
<option>My Option</option>
</select>
If you don't need any empty option at first, try this first line:
<option style="display:none"></option>
just use "..option hidden selected.." as default option
I guess a good idea would be to use the radio buttons, set #1 as default and hide it, give it for example a
name="init" and a value="null" or whatever, up to you!
this way the radio buttons list has a value definitely, but default of null can be used logically!
I think it's not necessary to elaborate further, since the idea can easily be implemented with display: none; or visibility: hidden;
... whereas I think the first one display: none; is the better option:
In react, you can give a dummy value (say -1) with select tag as below and same value can be used with this disabled option of yours. (WORKED FOR ME)
const nonEmpty = selected[identifierField] || false;
<select
onChange={(e) => {
onSelect(
options.find((option) => option[identifierField] === e.target.value)
);
}}
value={nonEmpty || -1}
>
<option disabled value={-1}>Select Option</option>
{options.map((option) => (
<option key={option[identifierField]} value={option[identifierField]}>
{option[displayField]}
</option>
))}
</select>
option style="display:none"
Is bad solution for Tablet: iPad Pro / iOS 15 / Safari
An unnecessary row in the dropdown appears, only for real devices. Doesn`t reproduce on the emulator.
Try this:
<select>
<option value="">
<option>Option 1
<option>Option 2
<option>Option 3
</select>
Validates in HTML5. Works with required attribute in select element. Can be re-selected. Works in Google Chrome 45, Internet Explorer 11, Edge, Firefox 41.
Is there a way to add an additional 'submenu' to a dropdown list on a contact form? So it would technically work like a drop-down navigation.
Below is the drop-down list for my contact form. And i've been asked to see if I can add additional options to lets say, Existing Partner. So when they hover over that item it expands to other options.
<label for="hear">How did you hear about us? </label>
<select class="contact-drop-down" name="hear" id="hear">
<option>Click to choose</option>
<option value="1">Existing Partner</option>
<option value="2">Word of mouth</option>
<option value="3">Brochure</option>
<option value="4">Email mailshot</option>
<option value="5">Google</option>
<option value="6">Yahoo</option>
<option value="7">Bing</option>
<option value="8">Other search engine</option>
<option value="9">Other</option>
</select>
You can't expand on hover with the standard select within HTML, but you can with either Javascript or HTML5 and CSS3.
This site has a list of 30 examples of HTML5 navigation menus and this site has a large selection of Javascript and JQuery examples.
Hopefully one of these might help you get what you want.
You can use optgroup tag for this.
<select>
<optgroup label="Existing Partners">
<option value="existing_partner_a">Partner A</option>
<option value="existing_partner_b">Partner B</option>
<option value="existing_partner_others">Others</option>
</optgroup>
</select>
No you cannot add sub menu to actual dropdown control. But you may find many custom controls.
Check out this
Saurabh Goyal above suggested to use . I also thought of suggesting the same. But is used for categorization & I dont think thats what you want.
Try optgroup for this .for example
<select>
<optgroup label="Swedish Cars">
<option value="volvo">Volvo</option>
<option value="saab">Saab</option>
</optgroup>
<optgroup label="German Cars">
<option value="mercedes">Mercedes</option>
<option value="audi">Audi</option>
</optgroup>
</select>
how to disable the <option> in select menu? I can handle this situation in browser but I cant in iPhone. Except approved option I disabled all. Here I attached the screenshot. Can any one tell me how fix this? thanks in advance .
This is a known issue in Safari for iOS. You can do 2 things:
Remove the options you don't want to be visible from the list
Tell the user that he made an invalid selection when he tries to commit the form
No other options here...
There are some standard options, if you try then this type of issue will resolved.
Try to use group options this will work with all devices and web browsers.
Tested with Android and iPhone4 and iPhone4s
<optgroup label='field name 1'>
<option value='1'>Name 1</option>
<option value='2'>Name 2</option>
<option value='3'>Name 3</option>
</optgroup>
<optgroup label='field name 2'>
<option value='1'>Name 1</option>
<option value='2'>Name 2</option>
<option value='3'>Name 3</option>
</optgroup>
I need a way to have a multi-select box that has a disabled element. I want the box to look like:
All
-----or-----
option 1
option 2
with the "----or----" not being able to be selected. So far my code is pretty simple:
<select multiple size="4" >
<option value="0">All</option>
<option value="1">----or----</option>
<option value="2">option 1</option>
<option value="3">option 2</option>
</select>
But as of yet I have been unable to get the '----or----" disabled or unselectable. I've looked around and I'm not sure there is an HTML attribute that will disable it, but I'm really not sure and I'm also not sure this is the best way to present this option. Any help you can offer is greatly appreciated!
Maybe take a look at the optgroup element ?
<select multiple size="4" >
<option value="0">All</option>
<optgroup label="----or----"></optgroup>
<option value="2">option 1</option>
<option value="3">option 2</option>
</select>
