[login to view URL] We want to be able to right click on an element table/div/image and toggle a predefined list of style class's. eg. If i right click on an image. Cut Copy Paste - Image Properties - Styling >> Left Align (ToggleClass leftalign) >> Right Align (ToggleClass rightalign) >> Left Border (ToggleClass ImageShadowLeft) >> Right Border (ToggleClass ImageShadowRight) Any questions please ask. This is being used in asp.net, this should be configured as a 'plugin'. Thanks Tristan
