There is currently a Webkit only CSS property called -webkit-touch-callout which allows you to disable platform specific context menus when holding a touch target.

One use case: platform drag and drop

A long press on an anchor element (<a>) on a touch device will result in a context menu being shown (eg "open in new tab"). -webkit-touch-callout allows you to opt out of this behaviour.

Opting out of touch target behaviours is particular useful for platform powered drag and drop. Without -webkit-touch-callout:none on iOS, you cannot start a drag operation of an anchor without first seeing a link context menu.

This issue was brought to my attention due to a recent bug I raised for Chrome + Android, where there is currently no mechanism to opt out of touch callouts

Proposal

• I propose that the CSS specification adopts -webkit-touch-callout as the standard property touch-callout.
• I also propose that touch-callout match the specification as found on MDN for -webkit-touch-callout (and the Safari CSS reference)

Thank you for your consideration
