I have 4 radio buttons (A, B, C, D). When I click on the radio button A, there would be another 2 options - A1 and A2. The same will happen with the others. And if I choose D2, another 2 radio buttons would appear.
How can I do this in HTML?
HTML and CSS3-only version (Fiddle):
HTML for group "D" (other groups are similar)
<div>
<input type="radio" name="level0" value="D" id="D"/>
<label for="D">D</label>
<div class="sub1">
<div>
<input type="radio" name="level1" value="D0" id="D0"/>
<label for="D0">D0</label>
</div>
<div>
<input type="radio" name="level1" value="D1" id="D1"/>
<label for="D1">D1</label>
<div class="sub2">
<div>
<input type="radio" name="level2" value="D10" id="D10"/>
<label for="D10">D1-0</label>
</div>
<div>
<input type="radio" name="level2" value="D11" id="D11"/>
<label for="D11">D1-1</label>
</div>
</div>
</div>
</div>
</div>
CSS
.sub1, .sub2 { display: none; }
:checked ~ .sub1, :checked ~ .sub2 {
display: block;
margin-left: 40px;
}
If you want more radio buttons to appear when a certain one is selected, I would suggest not "nesting" them inside one another in the html. Have javascript display a hidden group or RBs when a one is selected.
Frankly, I think using radio buttons to make a select box appear would be much more user friendly, as its clear that you're selecting from a different group. Too many radio buttons always looks ugly.
Other problems with your code: id's should be unique, put the RB text beside the radio button as opposed to inside the tag, and avoid table based layout if possible. inline javascript and css should be avoided too, but as this is a code sample it actually makes it more readable. Oh, most importantly, you have the other buttons set to appear on onclick, so they won't go away if you unselect the RB :D
You can only use a specific id on one element in a document. You have to put different id's on each element and make them visible separately:
<input onclick="document.getElementById('extra1').style.visibility='visible';document.getElementById('extra2').style.visibility='visible';" type="radio" />Apple
<input type="radio" id="extra1" style="visibility:hidden" other choice here />
<input type="radio" id="extra2" style="visibility:hidden" other choice here />
#guffa I think I'll just modify your answer a bit. Put all the optional radio buttons inside a <div> element like this:
<input onclick='document.getElmentById("optional_buttons").style.display="block"' type="radio" />
<div id="optional_buttons" style="display: none;" >
optional radio buttons
</div>

I want to have a group of radio buttons, so that one of them appears twice.
The result would look like this:
The tricky point is that I want to achieve this in pure HTML/CSS (although I doubt CSS will help here).
Here is the code I wrote to produce the four radio buttons above:
<input type="radio" name="buttons" value="choice1" id="button1"/>
<label for="button1">Choice 1</label>
<input type="radio" name="buttons" value="choice1" id="button1"/>
<label for="button">Choice 1</label>
<input type="radio" name="buttons" value="choice2" id="button3"/>
<label for="button3">Choice 2</label>
<input type="radio" name="buttons" value="choice3" id="button4"/>
<label for="button4">Choice 3</label>
I naively thought that attributing the same value to the first to buttons would make them behave as one, but of course it doesn't.
Is it possible to achieve this behaviour without any JS?
Edit
This might sound strange, so here's my usecase.
What I ultimately want is to have a radio button storing a global state, and have access to it at multiple places.
For instance, suppose the following snippet:
.state-repeater {
visibility: hidden;
}
#button.state-repeater:checked > p {
color: blue;
}
<input type="radio" id="button" />
<label for="button">Button</label>
<!--
Lots of blocks; the two parts are totally uncorrelated;
so the classical sibling selector tricks do not work
-->
<input class="state-repeater" type=radio id="button" />
<p>The button is checked</p>
I want the <p> tag text to turn blue when the radio button is checked; however, due to the radio button being far from it, I need some kind of repeater.
Obviously, the approach of this snippet does not work.
Is it possible to "repeat" the information that the radio button is checked?
You'll need to use JS. There is no pure way. Maybe wrap the radio in an element that LOOKS like 2 radio buttons and when clicked they both LOOK like they've been selected. But if you need two actual radio buttons that work together, you are out of luck. And in any case the thing I described before would be a huge headache compared to using JS.
I can't figure out why the spacing between the radio input and link is different for the first element than for the other two.
Here is the HTML:
<div class="citationChoice">
<label for="mla">
<input type="radio" name="citation" value="mla" id="mla_button" checked="checked">
MLA
</label>
<label for="apa">
<input type="radio" name="citation" value="apa" id="apa_button">
APA
</label>
<label for="chicago">
<input type="radio" name="citation" value="chicago" id="chicago_button">
Chicago Manual of Style
</label>
</div>
jsFiddle
For some reason, without any css applied, the mla radio button is closer to the MLA link than the other radio buttons are to their adjacent links.
(I know the HTML is not completely correct. If at all possible, I have to leave the HTML as is.)
You had a space before <a and jsfiddle was interpreting that. The first MLA link did not have this space, that is why it sat closer to the radio button
BEFORE -
id="apa_button"> <a
AFTER FIX -
id="apa_button"><a
so using the twitter bootstrap CSS framework,
if you display this html it will show with the text under the radio button, i want them to show to the right * or left of the radio button
this works if you replace Gender with Gender it will have the desired effect
however i do not have control over changing the tag to a span tag (im using a java based framework)
however i can prefix and suffix the html - shown in the example below
######## ADD PREFIX HTML ############<input type="radio" checked name="optionsRadios" value="option1" />
<label>Gender</label>#######ADD ADD SUFFIX THML ############
ur a wizard if you can get this working!, thanks guys
<div class="clearfix">
<label id="optionsRadio">Gender</label>
<div class="input">
<ul class="inputs-list" wicket:id="gender">
<li>
<label>
<input type="radio" checked name="optionsRadios" value="option1" />
<label>Gender</label>
</label>
</li>
<li>
<label>
<input type="radio" name="optionsRadios" value="option2" />
<label>Gender</label>
</label>
</li>
</ul>
</div>
The radio buttons on the bootstrap demo page render as you expect so there is either something in your own CSS causing this or a problem with your markup.
My guess is that the problem is because you have your radio buttons and your labels nested inside another label. Try removing the wrapper label and see if that works.
The label element must not have any nested label elements.
I have this HTML and CSS
http://jsbin.com/uciya5/3/edit
where the problem is that the radio buttons are treated as individual elements and therefore inherent the properties of class="cellData". Notice how wide the radio buttons are spaced vertically.
<div class="cellData">
<input name="ctype" value="individuel" type="radio" checked/> Individuel <br>
<input name="ctype" value="course" type="radio" /> Course </div>
</div>
Is it possible to control this vertical spacing of the radio buttons, or perhaps wrap a DIV around them to protect them?
Update
Removed template tags.
You could add another class to the div containing radio buttons:
<div class="cellData cellRadios">
with CSS (similar to this):
.cellRadios { line-height: 1 }
See: http://jsbin.com/uciya5/2
Provided that in your CSS you define .cellRadios after .cellData, the line-height from .cellRadios will be the one that's applied.
I'd probably also change .cellRadios to a better name.
If you prefer it, you could instead wrap the radio buttons in an extra div, as you suggested in your question.
<div class="cellData">
<div class="cellRadios">
<input name="ctype" value="individuel" type="radio" <TMPL_VAR IN>/> Individuel
<br>
<input name="ctype" value="course" type="radio" <TMPL_VAR CO>/> Course
</div>
</div>
You could delete this from the CellData stye: line-height:4em
You could also try using a table, it would be a lot simpler.
What's the most appropriate, semantically correct way to label checkbox and radio elements? Obviously, giving each one a unique id attribute is an option and using that in id a <label for="">, but this seems like it would break the semantic grouping. Putting unenclosed text next to the input element just seems...wrong.
Edit:
Additionally, how should one denote the label for a group of such elements? (i.e. not the description of each option, but the description of the whole group)
Using <label for=""> is the correct way to do that. The grouping of radio buttons is done by denoting the group via the name attribute and individual elements via the id attribute. For example:
<input type="radio" name="rbg" id="rbg1"><label for="rbg1">Button One</label><br>
<input type="radio" name="rbg" id="rbg2"><label for="rbg2">Button Two</label><br>
<input type="radio" name="rbg" id="rbg3"><label for="rbg3">Button Three</label><br>
As for putting a label over the entire group, just put them in a container that has a text container above the stack of buttons (or checkboxes). Example:
<div>
<h3>My Radio Button Group</h3>
<input type="radio" name="rbg" id="rbg1"><label for="rbg1">Button One</label><br>
<input type="radio" name="rbg" id="rbg2"><label for="rbg2">Button Two</label><br>
<input type="radio" name="rbg" id="rbg3"><label for="rbg3">Button Three</label><br>
</div>
