Bonjour,
Tu peux mettre ce mode dans le fichier single-product.html :
{form_field field='quantity'}
<div class="form-group group-qty {if $error}has-error{elseif $value != "" && !$error}has-success{/if}">
<label for="{$label_attr.for}">{$label}</label>
{if $QUANTITY >= 12}
<select name="{$name}" class="form-control" id="{$label_attr.for}">
{for $will=1 to 12}
<option {if $QUANTITY == $will}selected="selected"{/if}>{$will}</option>
{/for}
</select>
{else}
<select name="quantity" class="form-control" >
{for $will=1 to $QUANTITY}
<option {if $QUANTITY == $will}selected="selected"{/if}>{$will}</option>
{/for}
</select>
{/if}
{if $error }
<span class="help-block"><i class="fa fa-remove"></i> {$message}</span>
{elseif $value != "" && !$error}
<span class="help-block"><i class="fa fa"></i></span>
{/if}
</div>
{/form_field}
