Validation of a constant in Dropdown

Question

I have a dropdown in which the values are called from a constant. Will it be possible to customize which items will only come out?
Let's say the status of the request is cancelled, then I should only cancelled in the dropdown. Then if the status is reviewing, I should only see reviewing and revising. etc

Dropdown:

Constant:

Code for Reference:
a!dropdownField( label: "Request Approval", labelPosition: "ABOVE", placeholder: "--- Select a Value ---", choiceLabels: cons!CRP_REVIEWSTATUS_LIST, choiceValues: cons!CRP_REVIEWSTATUS_LIST, value: ri!review.reviewStatus, saveInto: ri!review.reviewStatus, searchDisplay: "AUTO", required: false, validations: {} )

Got it.Our approach to status value is, that we have an individual constant for each value. Then we can reference each value clearly and also use it for comparisons.To get a list of all values, we then create an expression which returns a list of all the constants.In a task form, you could then just list the values you need for that form.And if you use a reusable component, you could create a local holding the values matching the current status. A decision table can do that as well.

Wouldn't it be easier to use a textField in readonly to display that value? This is what I am doing. DropDown for modification and a textField for display. Of course, you can also use a richTextField etc.
