Form Control ^commun

Possibilité de contrôle des formulaires (comme input et textarea) grâce à des styles personnalisés (tailles, états, etc...).

<div class="mb-3">
    <label for="exampleFormControlInput1" class="form-label">Email address</label>
    <input type="email" class="form-control" id="exampleFormControlInput1" placeholder="name@example.com">
</div>
<div class="mb-3">
    <label for="exampleFormControlTextarea1" class="form-label">Example textarea</label>
    <textarea class="form-control" id="exampleFormControlTextarea1" rows="3"></textarea>
</div>

Possibilité d'avoir des éléments un peu plus grands (.form-control-lg) et un peu plus petits (.form-control-sm).

<input class="form-control form-control-lg" type="text" placeholder=".form-control-lg" aria-label=".form-control-lg example">
<input class="form-control" type="text" placeholder="Default input" aria-label="default input example">
<input class="form-control form-control-sm" type="text" placeholder=".form-control-sm" aria-label=".form-control-sm example">

Possibilité de créer des blocs de textes dans le contexte de formulaire à l'aide de la classe .form-text.
Ce texte doit être associé au contrôle auquel il se rapporte à l'aide de l'attribut aria-describedby.

<label for="inputPassword5" class="form-label">Password</label>
<input type="password" id="inputPassword5" class="form-control" aria-describedby="passwordHelpBlock">
<div id="passwordHelpBlock" class="form-text">
    Your password must be 8-20 characters long, contain letters and numbers, and must not contain spaces, special characters, or emoji.
</div>

Possibilité d'utiliser .form-text dans un contexte "inline".

<div class="row g-3 align-items-center">
    <div class="col-auto">
        <label for="inputPassword6" class="col-form-label">Password</label>
    </div>
    <div class="col-auto">
        <input type="password" id="inputPassword6" class="form-control" aria-describedby="passwordHelpInline">
    </div>
    <div class="col-auto">
        <span id="passwordHelpInline" class="form-text">
            Must be 8-20 characters long.
        </span>
    </div>
</div>

Ajouter l'attribut disabled à un champ pour lui donner un aspect grisé et empêcher le focus.

<input class="form-control" type="text" placeholder="Disabled input" aria-label="Disabled input example" disabled>
<input class="form-control" type="text" value="Disabled readonly input" aria-label="Disabled input example" disabled readonly>

Ajouter l'attribut readonly pour empêcher la modification de la valeur d'un champ.
Ce dernier peut recevoir le focus, contrairement à l'attribut disabled.

<input class="form-control" type="text" value="Readonly input here..." aria-label="readonly input example" readonly>

Pour obtenir un rendu readonly avec un aspect de texte seul, il suffit de remplacer .form-control par .form-control-plaintext.

<div class="mb-3 row">
    <label for="staticEmail" class="col-sm-2 col-form-label">Email</label>
    <div class="col-sm-10">
        <input type="text" readonly class="form-control-plaintext" id="staticEmail" value="email@example.com">
    </div>
</div>
<div class="mb-3 row">
    <label for="inputPassword" class="col-sm-2 col-form-label">Password</label>
    <div class="col-sm-10">
        <input type="password" class="form-control" id="inputPassword">
    </div>
</div>

Exemple inline :

<form class="row g-3">
    <div class="col-auto">
        <label for="staticEmail2" class="visually-hidden">Email</label>
        <input type="text" readonly class="form-control-plaintext" id="staticEmail2" value="email@example.com">
    </div>
    <div class="col-auto">
        <label for="inputPassword2" class="visually-hidden">Password</label>
        <input type="password" class="form-control" id="inputPassword2" placeholder="Password">
    </div>
    <div class="col-auto">
        <button type="submit" class="btn btn-primary mb-3">Confirm identity</button>
    </div>
</form>

<div class="mb-3">
    <label for="formFile" class="form-label">Default file input example</label>
    <input class="form-control" type="file" id="formFile">
</div>
<div class="mb-3">
    <label for="formFileMultiple" class="form-label">Multiple files input example</label>
    <input class="form-control" type="file" id="formFileMultiple" multiple>
</div>
<div class="mb-3">
    <label for="formFileDisabled" class="form-label">Disabled file input example</label>
    <input class="form-control" type="file" id="formFileDisabled" disabled>
</div>
<div class="mb-3">
    <label for="formFileSm" class="form-label">Small file input example</label>
    <input class="form-control form-control-sm" id="formFileSm" type="file">
</div>
<div>
    <label for="formFileLg" class="form-label">Large file input example</label>
    <input class="form-control form-control-lg" id="formFileLg" type="file">
</div>

En cas d'utilisation d'un type="color", ajouter .form-control-color à l'input.

<label for="exampleColorInput" class="form-label">Color picker</label>
<input type="color" class="form-control form-control-color" id="exampleColorInput" value="#563d7c" title="Choose your color">

Les datalists permettent de lister des option de façon similaire aux select mais avec un affichage plus léger.
Attention à la prise en charge de cet élément selon les différents navigateurs.

<label for="exampleDataList" class="form-label">Datalist example</label>
<input class="form-control" list="datalistOptions" id="exampleDataList" placeholder="Type to search...">
<datalist id="datalistOptions">
    <option value="San Francisco">
    <option value="New York">
    <option value="Seattle">
    <option value="Los Angeles">
    <option value="Chicago">
</datalist>
