Custom menu for filter type?

I’m still having problems creating custom menus for certain parameters (Lfo waveform, Filter type and filter shapes). I can easily create them for most drop down menus except those. The found that I can make custom menus from lists in the parameter list that have a black popup menu and can’t from white drop down menus.

I can’t make them for these?


But can make them for these.

Does anyone know how I can make custom menus for the white menu items in the parameter list?
