Constructors

new(id : String, selected : String, options : Array(String), width : Float64 | Nil = nil, label : String | Nil = nil, max_height : Float64 = 220.0)

label pins a placeholder shown while NOTHING is selected (selected == "", like TextEdit's hint); it also leads the dropdown as the zero option — picking it reports "". width defaults to a fixed column (no measure-every-option pass — the option list is too long for that to be cheap). max_height caps the dropdown's scroll viewport.
