Eliminate Bootstrap's validation glyphs

Issue Description

I am attempting to eliminate the validation icons from Bootstrap, such as the "x" and "check" symbols. Despite my efforts to search thoroughly, I have been unable to locate where these icons are located in the code.

Code Sample

<link href="https://stackpath.bootstrapcdn.com/bootstrap/4.2.1/css/bootstrap.min.css" rel="stylesheet" />
<script src="https://code.jquery.com/jquery-3.3.1.slim.min.js"></script>
<script src="https://stackpath.bootstrapcdn.com/bootstrap/4.2.1/js/bootstrap.min.js"></script>
<form class="was-validated">
  <div class="form-group">
    <select class="custom-select" required>
      <option value="">Open this select menu</option>
      <option value="1">One</option>
      <option value="2">Two</option>
      <option value="3">Three</option>
    </select>
    <div class="invalid-feedback">Example invalid custom select feedback</div>
  </div>
</form>

Thank you for your assistance,
Luiz.

Answer №1

Before importing bootstrap.scss when compiling SCSS with BootStrap, you can add the following line:

$enable-validation-icons: false;

Answer №2

To eliminate the icon, you can simply set the background property to none for the specific CSS class/pseudo-class in question.

.was-validated .custom-select:valid {
  background-image: none;
}

.was-validated .custom-select:invalid {
  background-image: none;
}

If your aim is to remove the validation icons while preserving the arrow icons on the select input, you can do so by adjusting the background as follows:

.was-validated .custom-select:invalid {
     background: url("data:image/svg+xml,%3csvg xmlns='http://www.w3.org/2000/svg' viewBox='0 0 4 5'%3e%3cpath fill='%23343a40' d='M2 0L0 2h4zm0 5L0 3h4z'/></svg>") no-repeat right .75rem center/8px 10px;
}

For Bootstrap 4 users:

By setting the background image to none for the specified selector, you will retain the background color and dropdown button appearance.

.form-control.is-invalid{
    background-image: none;
}

For those utilizing Bootstrap's SASS/SCSS:

Answer №3

Learning Bootstrap 4:

.form-control.is-valid,
.form-control.is-invalid {
    background-image: none;
    padding-right: inherit;
}

Answer №4

I encountered a similar issue, but it was specifically with input fields that had the type=date. To resolve this, I found that adding padding-right: 0.75em; helped ensure that the calendar icon maintained its original padding without any strange movement.

Here is the CSS code I used:

/* Removing validation icons */
.form-control.is-invalid, .was-validated .form-control:invalid {
    background-image: none !important;
    border-color: #ced4da;
    padding-right: 0.75em;
}

.form-control.is-valid, .was-validated .form-control:valid {
    background-image: none !important;
    border-color: #ced4da;
    padding-right: 0.75em;
}

Answer №5

.custom-select.is-invalid, .was-validated .custom-select:valid,.custom-select.is-invalid, .was-validated .custom-select:invalid {
    background: url("data:image/svg+xml,%3csvg xmlns='http://www.w3.org/2000/svg' viewBox='0 0 4 5'%3e%3cpath fill='%23343a40' d='M2 0L0 2h4zm0 5L0 3h4z'/%3e%3c/svg%3e") no-repeat right .75rem center/8px 10px,url("data:image/vg+xml,%3csvg xmlns='http://www.w3.org/2000/svg' viewBox='0 0 8 8'%3e%3cpath fill='%2328a745' d='M2.3 6.73L.6 4.53c-.4-1.04.46-1.4 1.1-.8l1.1 1.4 3.4-3.8c.6-.63 1.6-.27 1.2.7l-4 4.6c-.43.5-.8.4-1.1.1z'/%3e%3c/svg%3e") no-repeat center right 1.75rem/1.125rem 1.125rem !important;
    }
<link href="https://stackpath.bootstrapcdn.com/bootstrap/4.2.1/css/bootstrap.min.css" rel="stylesheet" />
<script src="https://code.jquery.com/jquery-3.3.1.slim.min.js"></script>
<script src="https://stackpath.bootstrapcdn.com/bootstrap/4.2.1/js/bootstrap.min.js"></script>

<form class="was-validated">
  <div class="form-group">
    <select class="custom-select" required>
      <option value="">Open this select menu</option>
      <option value="1">One</option>
      <option value="2">Two</option>

Answer №6

Success!

To make it work, you need to delete the following code 

, error_class: 'is-invalid', valid_class: 'is-valid'
located in simple_form_bootstrap.rb

Answer №7

This specific CSS class has proven effective in my experience, allowing you to apply it to any input or select component class to prevent validation.

These styles will specifically impact input fields.

.was-validated .prevent-validation.form-control:valid,
.was-validated .prevent-validation.form-control.is-valid
{
    padding: 0.375rem 0.75rem;
    border-color: #ced4da;
    background-image: none !important
}

By setting the background-image property to none, both the checkmark and 'x' symbols will be hidden.

This CSS class is designed for select components.

.was-validated .prevent-validation.form-select:valid,
.was-validated .prevent-validation.form-select.is-valid{
    padding: 0.375rem 0.75rem;
    border-color: #ced4da;
    --bs-form-select-bg-icon: none !important
}

Setting the '--bs-form-select-bg-icon' property to none will only hide the Bootstrap form verification icon, leaving the select arrow visible.
