Scusate ho il seguente codice, avrei bisogno di aggiungere la classe .pippo allo span question-gis quando la classe form-control dentro la select è focus. Potete aiutarmi?Codice:<div id="div_custom_attribute" hidden class="margin-top-10 justify-content-between "> <span class="help question-gis" data-container="body" data-toggle="popover" data-placement="left" title="Nota Bene" data-content="eventuale testo" > <i class="fas fa-question-circle font-blue-steel padding-left-5" style="margin-top: 11px;"></i> </span> <select id="custom_attribute" name="order_status" class="form-control form-filter item2" style="border-left: 0px"> </select> <a href="javascript:;" class="layer-upload input-group-addon btn blue-steel fileinput-exists item1" id="btn-upload-custom-building" style="padding: 6px 11px;" title="carica file"><i class="fas fa-upload text-white"></i></a> </div>
Grazie
