Wix Slide-Down Accordion Section

I need a custom accordion built on my Wix site. Each row will show a package category title and, when clicked, must slide down to reveal four static package cards that I’ll provide. The motion should be a smooth slide-down animation, and only one row may stay open at a time—opening a new row automatically closes the previous one. No sliders or carousels; the cards simply appear within the dropdown space.

I will supply all card designs, copy, and colour specs. Your task is to implement the accordion inside Wix, ensure it’s responsive on desktop and mobile, and leave me with a reusable component that I can maintain going forward.

Deliverable:
• Fully functional, single-open, slide-down accordion section integrated on my Wix page and tested across breakpoints.

Let me know your approach (native Wix tools or Velo code) and estimated turnaround time so we can get started right away.
