Dropdown list in input parameters of Custom Indicator

 
Metaquotes,

Congratulations on the development of an excellent trading platform MT4.

I have a request. Can you incorporate a method of creating a dropdown selection for input parameters of a custom indicator. This would be similar to how the bool variable is displayed in the input parameters except that there would be multiple options displayed in a dropdown list instead of just true/false.

I have several indicators that would be facilitated by this capability. tia.
