Hide Codes adjacent to Action drop down while changing Salary

Content

Hi Folks,

We don't want the Action Codes to be visible adjacent to Action while changing the Salary from Person Management.

Navigation: My Client Groups - Person Management - Search for an Employee - On actions menu - Compensation - Change Salary - Propose New Salary

Here we are seeing the Action Codes adjacent to Action drop down while changing the Salary.
And we don't want to see that.

Any Ideas, how can we hide that?
