In some cases the display does not match the instructions on screen.
On a seller's listings page (e.g. https://www.ebid.net/uk/items/20sent06) are the instructions:
Use the categories on the left or search box to refine
but the categories list 'Their Subcategories' is not being displayed and is hidden behind the icon at top-right. Even when you click the icon the list appears above the text and not to the left.
Rotating the device from portrait to landscape does not correct the display (plus the icon disappears leaving no way to access the list) and you have to refresh the page to correct it.
