The way to use the Bootstrap radio button:

For you to set up a radio button we primarily really need a

<div>

element to wrap it within with the

.form-check

or else

.form-check-inline

utilized. The first class will assign the Bootstrap Radio Set a block look and the next will straighten the element inline together with ultimately a number of more others such as it. These are truly new classes for Bootstrap 4-- in the past editions they used to be defined as

.radio

and

.radio-inline

In the case that you want the radio button to arrive on webpage but to become disabled for clicking on-- ensure you've likewise provided the

.disabled

class here.

In the

.form-check

element we should really initially include a

<label>

with the

.form-check-label

class specified and inside it an

<input>

plus the

.form-check-input

class and some attributes employed like

type = “radio”

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

supposing that you possess a number of radio buttons detailing a few solutions a user should get from they ought to come with the similar name and yet other special

id = “ ~ unique ID ~ “

attribute and a

value=” ~some value here ~ ”

attribute. Lastly assuming that you're targeting to disable the control -- also incorporate the

disabled

attribute to the

<input>

element.

This is in addition the location to specify in the case that you want the radio control to at first load as checked when the page gets loaded. Supposing that this is what you're after-- as an alternative to

disabled

put in the

checked

attribute to the

<input>

In case you turn out to purposefully or else accidentally provide a few radio buttons along with the

checked

attribute-- the last one read will be as well the one showing as looked at web page load.

Checkbox plus Bootstrap Radio Event situations

The checked state for these buttons is only updated via click event on the button.

Take note of that pre-checked buttons need you to manually include 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 possibility

We may choose input features of the radio form if we want the user to pick just one of a variety of opportunities. ( learn more here)

Solely just one might be chosen when there is higher than a single component of this style with the similar value within the name attribute.

<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">

      </span>
      <input type="text" class="form-control" aria-label="Text input with radio button">
    </div>
  </div>
