position: sticky not workingThe element with position: sticky does not stick as expected.
An ancestor element has overflow: hidden, overflow: auto, or overflow: scroll set, which creates a new scrolling context. The sticky element can only stick within its scrolling container. Also, the element needs a threshold (top, bottom, left, or right) to be set.
Remove overflow: hidden from ancestor elements. Set a threshold value (top: 0). Ensure the sticky element's container is tall enough for scrolling. Check that no ancestor creates an unwanted scroll container.
