MATLAB: Drop-down menu in simulink

MATLABsimulink

Hi every one,
After long search, I was not able to find a proper answer for my request. Instead of using a simple constant block, I would like to insert a BLOCK in the simulink as an input data( constant input). This block should be as a DROP-DOWN menu. For example: when I click on it, it will give me three options for the temprature and I can choose one of them as an input to my system.
please support me if any one has and idea or solution.
Thank you

Hi,
One idea of creating drop-down option for input constant is to have this block under a subsystem that have to be converted into a mask. Then using Mask edit options: Popup control GUI button and Popup options, intialization options...
if you'd like to create not a drop-down but just a user entry box option, then it is much simpler.
Good luck.
