Today I created a rendering component which has around 10 fields but the whole component is not editable in Experience Editor. I decided to use Edit Frame from Glass Mapper. The BeginEditFrame wants all the editable fields as a parameter. But for around 10 fields not that comfortable.
The following code snippet creates an Edit Frame only with 1 field.
|@using (@Html.Glass().BeginEditFrame(Model, "Edit The Component", x => x.Image))|
|// your code|
