Hiding the column from downdown display

[nischal]

In the image , i have some columns which are hidden on loading of gantt chart,
But it is still listed as part of columns field dropdown
I want to hide them from viewing, how do i achieve it.
( I do not want it to be listed in that dropdown either).
