The best way to use the Bootstrap radio button:

If you want to build a radio button we initially need a

<div>

element to wrap it inside with the

.form-check

as well as

.form-check-inline

utilized. The first class will assign the Bootstrap Radio Toggle a block appeal and the second will line up the element inline together with ultimately a number of more others like it. These are really fresh classes for Bootstrap 4-- in the previous versions they used to be specified as

.radio

and

.radio-inline

Assuming that you want the radio button to take place on page however to get disabled for clicking on-- ensure you have actually as well incorporated the

.disabled

class here.

Inside the

.form-check

element we should certainly first add in a

<label>

with the

.form-check-label

class assigned and inside it an

<input>

plus the

.form-check-input

class and several attributes employed such as

type = “radio”

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

assuming that you have a number of radio buttons defining a few options a site visitor ought to pick up from they should come with the similar name but other special

id = “ ~ unique ID ~ “

attribute and a

value=” ~some value here ~ ”

attribute. At last in case you're intending to disable the control -- as well add in the

disabled

attribute to the

<input>

element.

This is additionally the area to specify assuming that you want the radio control to primarily load as checked as soon as the page gets loaded. Supposing that this is actually what you're after-- as an alternative to

disabled

bring in the

checked

attribute to the

<input>

In case you happen to on purpose or accidentally bring in a few radio buttons along with the

checked

attribute-- the last one read will definitely be additionally the one presenting as looked at webpage load.

Checkbox and Bootstrap Radio Button representations

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

Bear in mind that pre-checked buttons demand you to manually add in the

.active

class to the input's

<label>

Checkbox

  <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>

  </label>

</div>

Radio button opportunity

<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>
