Bootstrap 4 Custom Form

For even more customization and cross browser consistency, use custom form elements to replace the browser defaults styling.

Checkboxes

Each checkbox input and label pairing is wrapped in a div to create our custom control.

Example 1: Custom Checkboxes

<div class="custom-control custom-checkbox">
  <input type="checkbox" class="custom-control-input" id="customCheck1">
  <label class="custom-control-label" for="customCheck1">Check this custom checkbox</label>
</div>

Custom checkboxes can also utilize the :indeterminate pseudo class when manually set via JavaScript

Example 2: Checkboxes with indeterminate state

<script>
    $(document).ready(function(){
        $('.c2').prop('indeterminate', true);
    });
</script>
<div class="custom-control custom-checkbox">
    <input type="checkbox" class="custom-control-input c2" id="customCheck2">
    <label class="custom-control-label" for="customCheck2">Check this custom checkbox</label>
</div>

Radio Button

<div class="custom-control custom-radio">
  <input type="radio" id="customRadio1" name="customRadio" class="custom-control-input">
  <label class="custom-control-label" for="customRadio1">Toggle this custom radio</label>
</div>
<div class="custom-control custom-radio">
  <input type="radio" id="customRadio2" name="customRadio" class="custom-control-input">
  <label class="custom-control-label" for="customRadio2">Or toggle this other custom radio</label>
</div>

Inline Radio Button

<div class="custom-control custom-radio custom-control-inline">
  <input type="radio" id="customRadioInline1" name="customRadioInline1" class="custom-control-input">
  <label class="custom-control-label" for="customRadioInline1">Toggle this custom radio</label>
</div>
<div class="custom-control custom-radio custom-control-inline">
  <input type="radio" id="customRadioInline2" name="customRadioInline1" class="custom-control-input">
  <label class="custom-control-label" for="customRadioInline2">Or toggle this other custom radio</label>
</div>

Switches

A switch has the markup of a custom checkbox but uses the .custom-switch class to render a toggle switch.

<div class="custom-control custom-switch">
  <input type="checkbox" class="custom-control-input" id="customSwitch1">
  <label class="custom-control-label" for="customSwitch1">Toggle this switch element</label>
</div>
<div class="custom-control custom-switch">
  <input type="checkbox" class="custom-control-input" disabled id="customSwitch2">
  <label class="custom-control-label" for="customSwitch2">Disabled switch element</label>
</div>

Select menu

Custom select menus need only a custom class, .custom-select to trigger the custom styles. Custom styles are limited to the select initial appearance and cannot modify the option due to browser limitations.

<select class="custom-select">
  <option selected>Open this select menu</option>
  <option value="1">One</option>
  <option value="2">Two</option>
  <option value="3">Three</option>
</select>

Range

Create custom <input type="range"> controls with .custom-range. The track (the background) and thumb (the value) are both styled to appear the same across browsers.

<label for="customRange1">Example range</label>
<input type="range" class="custom-range" id="customRange1">

Range inputs have implicit values for min-0 and max-100, respectively. You may specify new values for those using the min and max attributes.

<label for="customRange2">Example range</label>
<input type="range" class="custom-range" min="0" max="5" id="customRange2">

File browser

<div class="custom-file">
  <input type="file" class="custom-file-input" id="customFile">
  <label class="custom-file-label" for="customFile">Choose file</label>
</div>

Add the following code if you want the name of the file appear on select

$(".custom-file-input").on("change", function() {
  var fileName = $(this).val().split("\\").pop();
  $(this).siblings(".custom-file-label").addClass("selected").html(fileName);
});
