Re: Tab controls and WCAG 1.4.10 Reflow

This exact issue came up last week in an IAAP discussion, and our team discussed it internally for more than an hour. It seems simple at first, but it raises the question of what "scrolling" means, among other things. The WCAG authors must have assumed it's obvious, because they do not provide a definition.

Opinion was split, both in IAAP and in our team. My view is that a Tab component does not require two-dimensional layout, and that the tabs can perfectly well wrap onto two or more lines. Indeed, I failed one of our clients' sites on this exact issue.
