If I have a master component that's now been included on many pages, I can see that I can edit it to update the contents that are already in there. But I can't seem to figure out how to add say new images to the component. You can't just drag something inside to the component.
At the moment the only thing that I can see looks close is to ungroup the component and then regroup it with the new images, but I don't think that's going to work.
Right, that is way that you can add anything into component and create a new one
Ok thanks I just want to be clear I understand this response. If you have to update a component by creating a new component, then what does that mean for the old component that's already being used in say 5 different pages? Will that be updated too?
Try copy/paste. If you select an element within the component, you should be able to paste an image into the component.
