I am trying to label features via ArcGIS Online and I want to have features labeled differently depending on their region, but all the 4 features I have are under the same layer. So, in ArcMap I can actually change each feature under the layer to have different colored halos, colored font, etc. but in Arc GIS online I cannot find a way to do the same thing. Is there any way to change features under a layer individually? Thank you for your time!
