Dragging Movements
All functionality that uses a dragging movement for operation must be achievable by a single pointer without dragging, unless dragging is essential.
What it requires
WCAG 2.2 SC 2.5.7 protects users with motor disabilities who cannot perform sustained drag gestures. Drag-only sliders, drag-only sorting, drag-only swatch carousels, and drag-only image zoom all fail unless an alternative single-tap path exists.
Common alternatives: tap-to-select instead of drag-to-rearrange; +/- buttons next to a price-range slider; tap-to-advance arrows next to a swipe carousel; pinch-to-zoom replaced by a tap-to-zoom button.
Common Shopify failure
Product image gallery that requires horizontal swipe with no left/right navigation arrows. Variant swatch picker that scrolls horizontally with no scroll-buttons. Price-range filter slider with no numeric +/- input.
How to fix it
AccessComply adds prev/next buttons to swipe carousels and number-input alternatives next to drag-only sliders. Where dragging is genuinely essential (e.g., signature pad), the page is documented as such.
