The agent thinks

“I am on the home page and will select the Aero Run 2 product to view its details.”

How far it got

  5. Checkout

The agent stops at the checkout, before any personal or payment details.

The obstacle in this store

What is in the way

The size is picked from a decorative JavaScript list. The real select field is hidden and the list items are not buttons.

How a store fixes it

Keep a visible native <select>, or give the list ARIA roles (listbox and option).

In the obstacle registry: CIB-005

What happened

  • Clicked 4 times in a row on the same page without finding a way forward.
  • 1 action did not work.
  • Visited 5 different pages.
Why it stopped

“The size dropdown options (40–45) are not exposed as interactive elements, and clicking the dropdown container only toggles it without selecting a size.”
