In the configure custom attribute display of the pop-ups, is there a way to have the URL hyperlink show if there is a URL in that field, and to not have anything show if there is no URL in the field? We have it written now with a More Information hyperlinked to a URL that is given in the field. However, not all of our attributes have a URL. This is a layer that will be frequently edited and updated, so we would like to avoid filtering the layer and creating multiple versions of it.
