Nav bar drop down not showing up

Hi! I’m new to Webflow and these forums have been super helpful but I can’t seem to figure out why my nav bar drop down isn’t working. I did accidentally delete my menu button and I’m hoping that’s not the reason why this is happening because then I might have to rebuild my entire nav bar. aNy help is welcome!

You can place a new nav bar below your existing and then drag the button from the new one into the existing
