我遇到了selectpicker的问题。当我使用它时，输入不包裹。
例如：
<div class="form-group col-sm-6">
<label for="sesso">Sesso dei partecipanti</label>
<select class="selectpicker" data-live-search="true" name="sesso" id="sesso">
<option value="" disabled="" selected="selected" class="hide-option">Seleziona</option>
<option value="M">Maschile</option>
<option value="F">Femminile</option>
<option value="X">Misto</option>
</select>
</div>
标签标签后没有selectpicker输入换行：
<div class="form-group col-sm-6">
<label for="numero_partecipanti">Numero Partecipanti</label>
<input type="text" class="form-control" name="numero_partecipanti" id="numero_partecipanti">
</div>
