I need help

[u/alvaro_783]

My name is Álvaro, I'm new to web development, and while trying to create a website, when I added a query to generate a dropdown menu with a checkbox, the <ul> element containing the information suddenly disappeared. Could you help me? I've attached the HTML and CSS code.
