The best way to apply the Bootstrap radio button:

In order to develop a radio switch we first require a

<div>

element to cover it inside with the

.form-check

as well as

.form-check-inline

employed. The 1st class will attach the Bootstrap Radio Example a block form and the next will straighten the element inline along with eventually a few more others similar to it. These are truly new classes for Bootstrap 4-- in the earlier editions they used to be specified as

.radio

and

.radio-inline

In the case that you wish the radio button to be on web page however to get disabled for clicking on-- ensure that you've as well provided the

.disabled

class here.

In the

.form-check

element we should certainly first incorporate a

<label>

along with the

.form-check-label

class assigned and within it an

<input>

plus the

.form-check-input

class and a number of attributes applied such as

type = “radio”

name = “ ~ same name for all the options ~ ”

supposing that you have a number of radio buttons detailing a few solutions a visitor ought to get from they should carry the exact same name and yet different special

id = “ ~ unique ID ~ “

attribute as well as a

value=” ~some value here ~ ”

attribute. And finally supposing that you are actually targeting to disable the control -- additionally put in the

disabled

attribute to the

<input>

element.

This is in addition the location to define assuming that you wish the radio control to primarily load as checked when the webpage gets loaded. If this is what you are actually looking for-- as an alternative to

disabled

incorporate the

checked

attribute to the

<input>

In case you appear to on purpose or accidentally incorporate a few radio buttons with the

checked

attribute-- the last one read will certainly be as well the one displaying as checked on web page load.

Checkbox and Bootstrap Radio Set as an examples

The checked condition for all of these buttons is only updated via click event on the button. If you apply an additional procedure to upgrade the input-- e.g., with

<input type="reset">

or through manually applying the input's reviewed property-- you'll have to toggle

.active

on the

<label>

by hand.

Keep in mind that pre-checked buttons need you to manually bring in the

.active

class to the input's

<label>

Checkbox

<div class="btn-group" data-toggle="buttons">
  <label class="btn btn-primary active">
    <input type="checkbox" checked autocomplete="off"> Checkbox 1 (pre-checked)
  </label>
  <label class="btn btn-primary">
    <input type="checkbox" autocomplete="off"> Checkbox 2
  </label>
  <label class="btn btn-primary">
    <input type="checkbox" autocomplete="off"> Checkbox 3
  </label>
</div>

Radio

<div class="btn-group" data-toggle="buttons">
  <label class="btn btn-primary active">
    <input type="radio" name="options" id="option1" autocomplete="off" checked> Radio 1 (preselected)
  </label>
  <label class="btn btn-primary">
    <input type="radio" name="options" id="option2" autocomplete="off"> Radio 2
  </label>
  <label class="btn btn-primary">
    <input type="radio" name="options" id="option3" autocomplete="off"> Radio 3
  </label>
</div>

Radio button solution

We can easily employ input features of the radio style anytime we desire the user to go for only one of a set of alternatives. ( more hints)

As there is much more than a single component of this particular type along with the similar value with the name attribute, only one can possibly be selected.

<div class="row">
  <div class="col-lg-6">
    <div class="input-group">
      <span class="input-group-addon">
        <input type="checkbox" aria-label="Checkbox for following text input">
      </span>
      <input type="text" class="form-control" aria-label="Text input with checkbox">
    </div>
  </div>
  <div class="col-lg-6">
    <div class="input-group">
      <span class="input-group-addon">
        <input type="radio" aria-label="Radio button for following text input">
      </span>
      <input type="text" class="form-control" aria-label="Text input with radio button">
    </div>
  </div>
</div>
