Transforming check box to dropdown style

I am trying to implement a dropdown style faceting; however, I get empty dropdown menu.
I could have done it before but I lost the code because of of unintentional shutting down .
please advise what I’m missing right now.
Thank you.

My js code.
container: ‘#tag-list’,** **
attribute: ‘Tag’,


div id=“clear-refinements”>
select id=“tag-list”>
*I intentionally deleted < for displaying my html code here.

Hi @ynaka, Could you provide a codesandbox to demonstrate the issue? We have starter templates here.
