The instructions provided below describe how to set a single feature's symbology to be different than the rest of the layer. For example, you may have symbolized a polygon layer to be a single color but you would like to quickly set a particular feature to have a different symbol than the rest of the layer.
Follow the steps below.
- Right click the layer then click layer properties > symbology > categories > unique values > value field.
- Change "value field" to the field that identifies the feature you want to change the symbology for.
- Click add values and select the feature from the list then Click OK.
- Change the symbol properties by clicking the symbol.
Repeat steps 3 and 4 for as many features as you like. If you have many features you would like to change the symbology for, consider using a different renderer that will symbolize automatically.
