Yii2 - Only one select get options - php

Question

I got an issue. I have 3 select inputs, that i want to fill in with same options. First input gets options, but another two don't. I've tried everything. Last thing, that i tried was select 3 different queries and fill each one separately. Unfortunately, i get same issue.
Thanks for advices.
Controller
$dataPbxObj1 = Sipend::find()
->select('cc_sip_end.*')
->leftJoin('cc_reseller_to_pbx', '`cc_reseller_to_pbx`.`ID_PBX` = `cc_sip_end`.`id`')
->where(["in", "cc_reseller_to_pbx.id_cc_reseller", $reseller->id_cc_reseller])->all();
$dataPbxObj2 = Sipend::find()
->select('cc_sip_end.*')
->leftJoin('cc_reseller_to_pbx', '`cc_reseller_to_pbx`.`ID_PBX` = `cc_sip_end`.`id`')
->where(["in", "cc_reseller_to_pbx.id_cc_reseller", $reseller->id_cc_reseller])->all();
$dataPbxObj3 = Sipend::find()
->select('cc_sip_end.*')
->leftJoin('cc_reseller_to_pbx', '`cc_reseller_to_pbx`.`ID_PBX` = `cc_sip_end`.`id`')
->where(["in", "cc_reseller_to_pbx.id_cc_reseller", $reseller->id_cc_reseller])->all();
$dataPbx1 = ArrayHelper::map($dataPbxObj1,'id','popis');
$dataPbx2 = ArrayHelper::map($dataPbxObj2,'id','popis');
$dataPbx3 = ArrayHelper::map($dataPbxObj3,'id','popis');
View (all this selects are same)
<?=$form->field($modelSip, 'ID_PBX')->widget(Select2::className(),
["data" => $dataPbx3,'hideSearch' => true]) ?>

You probably needs to use unique IDs - by default Yii generates ID based on field name, but with 3 identical fields, IDs will be the same, and Select2 init will apply only for first of them.
<?=$form->field($modelSip, 'ID_PBX')->widget(Select2::className(), [
'options' => ['id' => 'ID_PBX1'],
'data' => $dataPbx,
'hideSearch' => true,
]) ?>
<?=$form->field($modelSip, 'ID_PBX')->widget(Select2::className(), [
'options' => ['id' => 'ID_PBX2'],
'data' => $dataPbx,
'hideSearch' => true,
]) ?>
<?=$form->field($modelSip, 'ID_PBX')->widget(Select2::className(), [
'options' => ['id' => 'ID_PBX3'],
'data' => $dataPbx,
'hideSearch' => true,
]) ?>
BTW: you don't need to query options list 3 times, you can do it once and use the same result in 3 fields.
