Change Curtain Panel material

[soccerseanw526780]

I brought in a nana wall, i changed the mullions but i want to change material of the frame which is the curtain panel, so I can edit curtain panel material?

If the curtain panel doesn't have a parameter for material, you should select a curtain panel and Edit Family. Select the object that will have the new material and assign it a material parameter. I found this post when I searched "revit family material parameter":
