In your htmloptionsarray just do like below:
在您的htmloptions阵列中，只需执行以下操作：
dropDownList(ArrayHelper::map(TblCategory::find()->all(), 'int_category_id', 'str_category'), array('onchange'=>'getData()','class' =>'form-control','prompt'=>'Select Room Category'))
Each key and value in htmloptionsarray will be converted to html attributes, for example:
htmloptions数组中的每个key和value都会被转换成html属性，例如：
'key'=>'value'
Will be shown as :
将显示为：
<tag key="value" />

Here's how I did it:
这是我如何做到的：
echo $form->field($flightSearchForm, "lastDepartTimeChange",
['options' => ['class' => 'col-xs-12',
'onchange' => "changeHidden(\"departFlightTimeMin\")"]
])->widget(\yii\jui\SliderInput::classname());
As you can see, I just put it in the HTML options array which is the third input to the $form->field function. Hope this helps!
如您所见，我只是将它放在 HTML 选项数组中，这是 $form->field 函数的第三个输入。希望这可以帮助！
