Bootstrap Forms documentationBasic forms
Textual form controls—like <input>s, <select>s, and <textarea>s—are styled with the .form-control class. Included are styles for general appearance, focus state, sizing, and more.
<form>

<label class="form-label" for="exampleFormControlInput1">Text</label>
<input type="text" id="exampleFormControlInput1" class="form-control" placeholder="John Doe">
</div>
<div class="mb-3">

<option>4</option>
<option>5</option>
</select>
</div>
<div class="mb-3">
<label class="form-label" for="exampleFormControlSelect2">Multiple select</label>
<select id="exampleFormControlSelect2" class="form-control" size="3" multiple>

<label class="form-label" for="exampleFormControlTextarea1">Textarea</label>
<textarea id="exampleFormControlTextarea1" class="form-control" placeholder="Textarea field" rows="4"></textarea>
</div>
</form>
Sizing
Set heights using classes like .form-control-lg and .form-control-sm.
<input class="form-control form-control-lg" type="text" placeholder=".form-control-lg">
<input class="form-control" type="text" placeholder="Default input">
<input class="form-control form-control-sm" type="text" placeholder=".form-control-sm">
Form select
Custom <select> menus need only a custom class, .form-select to trigger the custom styles. Custom styles are limited to the <select>’s initial appearance and cannot modify the <option>s due to browser limitations.
<!-- Select -->
<select class="form-select">
<option selected="">Open this select menu</option>
<option value="1">One</option>
<option value="2">Two</option>
<option value="3">Three</option>
</select>
<!-- End Select -->
You may also choose from small and large custom selects to match our similarly sized text inputs.
<!-- Select -->
<select class="form-select form-select-lg mb-3">
<option selected="">Open this select menu</option>
<option value="1">One</option>
<option value="2">Two</option>
<option value="3">Three</option>
</select>
<!-- End Select -->
<!-- Select -->
<select class="form-select form-select-sm">
<option selected="">Open this select menu</option>
<option value="1">One</option>
<option value="2">Two</option>
<option value="3">Three</option>
</select>
<!-- End Select -->
