Я новичок в кодировании, и я хочу добавить поле рождения в моей форме. Как отредактировать код выбора даты bootstrap код, что происходит неправильно. насколько я знаю, это конечная дата бесконечность, но все равно код работает, если я его отредактирую.
мой html код для типа ввода
<div class="form-group">
<label for="field-1" class="col-sm-3 control-label">Birthdate :</label>
<div class="col-sm-5">
<input type="text" name="birthdate" id="birthdate" class="form-control datepicker" data-format="yyyy-m-d" required>
</div>
