When we use multiple radio buttons with same name in Yii
many people have the problem on getting the value of the selected radiobutton.
The radioButtonList can be used for that, but if we need to use radioButton itself to place the button any where in a view, we need to include one more parameter in htmloption array().
The yii2-field-range extension enables you to easily setup ActiveField range fields with Bootstrap styling. You basically can setup two attributes joined together like a single field with combined validation error block.
