I displayed my roads with the symbology, categories unique values, feature so that all the roads have a unique color asssociated to them. When I display it in the legend I get a huge list. I only want a few roads on my legend rather than all of them.
Example: I have 10 different state highways each with the same color red. In my legend I only want one red line that refers to all the state highways rather than ten red lines in the legend. I hope someone can help. Thanks.
One thing you could try is duplicating your layer with the ten red roads, and then removing nine of them. Then you've got a single item which you can customize and add to the legend. This isn't the most correct way to do it, but it works in a pinch.
