We have a content type that in addition to the body field it has a field for Image and another field for Video.
Both video and image are currently displayed at the top of the node, in Node > Manage Display. But if there is already a value for video field, that should be all that needs to display. Unless the video field has no value in which case, display the image field.
In other words, we want to have a condition where the image field is hidden IF there is a value for the Video field. If no data is present for video filed, display image.
Does anyone have an idea of how this can be accomplished?
