Select

Personaliza los <select> nativos con CSS personalizado que cambia la apariencia inicial del elemento.

Por defecto

Los menús <select> personalizados solo necesitan una clase personalizada, .form-select para activar los estilos personalizados. Los estilos personalizados están limitados a la apariencia inicial de <select> y no pueden modificar <option> debido a las limitaciones del navegador.

<select class="form-select" aria-label="Default select example">
  <option selected>Abre este menú select</option>
  <option value="1">Uno</option>
  <option value="2">Dos</option>
  <option value="3">Tres</option>
</select>

Dimensionamiento

También puedes elegir entre selects pequeñas y grandes para que coincidan con nuestras entradas de texto de tamaño similar.

<select class="form-select form-select-lg mb-3" aria-label="Ejemplo de .form-select-lg">
  <option selected>Abre este menú select</option>
  <option value="1">Uno</option>
  <option value="2">Dos</option>
  <option value="3">Tres</option>
</select>

<select class="form-select form-select-sm" aria-label="Ejemplo de .form-select-sm">
  <option selected>Abre este menú select</option>
  <option value="1">Uno</option>
  <option value="2">Dos</option>
  <option value="3">Tres</option>
</select>

El atributo multiple también es compatible:

<select class="form-select" multiple aria-label="Ejemplo de multiple select">
  <option selected>Abre este menú select</option>
  <option value="1">Uno</option>
  <option value="2">Dos</option>
  <option value="3">Tres</option>
</select>

Al igual que el atributo size:

<select class="form-select" size="3" aria-label="Ejemplo de select de tamaño 3">
  <option selected>Abre este menú select</option>
  <option value="1">Uno</option>
  <option value="2">Dos</option>
  <option value="3">Tres</option>
</select>

Deshabilitado

Agrega el atributo booleano disabled en un select para darle una apariencia atenuada y eliminar los eventos de puntero.

<select class="form-select" aria-label="Ejemplo de select deshabilitado" disabled>
  <option selected>Abre este menú select</option>
  <option value="1">Uno</option>
  <option value="2">Dos</option>
  <option value="3">Tres</option>
</select>
