Conditional Logic in options for select box

is it possible to have a different options for each select box?

i have this code for selectbox(Lets say the values of this selectbox is type1 and type2)

array(
	'name' => 'Type',
	'id'   => 'pr_type',
	'placeholder' => 'Select Type',
	'type'        => 'taxonomy',
	'taxonomy'    => 'bedroom_product_type',
	'field_type'  => 'select',
	'query_args'  => array(),
)

Then this selectbox will show if the user select "type1"

array(
        'hidden'      => array('pr_type', '!=', 'type1'),
	'name'        => 'Size',
	'id'          => 'pr_size',
	'placeholder' => 'Select Size',
	'type'        => 'select',
	'options'     => array(
		'option_a1' => 'Option A1',
		'option_a2' => 'Option A2',
                'option_a3' => 'Option A3',
	),
),

Then if the user selects "type2" this is the selectbox

array(
        'hidden'      => array('pr_type', '!=', 'type2'),
	'name'        => 'Size',
	'id'          => 'pr_size',
	'placeholder' => 'Select Size',
	'type'        => 'select',
	'options'     => array(
		'option_b1' => 'Option B1',
		'option_b2' => 'Option B2',
	),
),

This codes doesn't work when updating only for saving for the first time

i want to use only one id for this
