Safari is still missing drag image (regression). Tested manually basic DnD and Grid Dnd on Windows IE11 and Edge. Drop event for both is still not working properly #9174. --- documentation/advanced/advanced-dragndrop.asciidoc | 9 ++++----- 1 file changed, 4 insertions(+), 5 deletions(-) (limited to 'documentation/advanced/advanced-dragndrop.asciidoc') diff --git a/documentation/advanced/advanced-dragndrop.asciidoc b/documentation/advanced/advanced-dragndrop.asciidoc index 804224d317..bcdfb2343d 100644 --- a/documentation/advanced/advanced-dragndrop.asciidoc +++ b/documentation/advanced/advanced-dragndrop.asciidoc @@ -130,17 +130,16 @@ When data is dragged over a drop target, the __v-drag-over__ class name is appli The __drop effect__ allows you to specify the desired drop effect, and for a succesful drop it must match the allowed effect that has been set for the drag source.
