I am new to ESRI and I would like to know if there is a way to create a sub-layer for a certain attribute with the main layer. If this is possible please let me know the steps or where I can find information to create this layer.
Then you should be able to symbolize by Category. Right click the layer, select properties, select Symbology, and symbolize by Category. Select the one field that has your values and click Add all Values. You should then be able to switch the symbology for both the Aerial and Underground features. I hope this helps!
For an example I am inputting fiber optic cable with attributes and my layer is for all fiber for a certain customer now in that layer I would like to style all aerial attribute to a certain color & all underground to a certain color. Does this clarify?
