Parameters to be shown

How do you show two different parameters independent from each other?

(If the first is turned off, the second isn't visible too)

using System;
using cAlgo.API;
using cAlgo.API.Internals;
using cAlgo.API.Indicators;
using cAlgo.Indicators;

namespace cAlgo.Indicators
{
    [Indicator(IsOverlay = true, AutoRescale = false, TimeZone = TimeZones.UTC, AccessRights = AccessRights.None)]
    public class MaVe : Indicator
    {    

        [Parameter("Show Name1", DefaultValue = true)]
        public bool ShowName1 { get; set; }
        [Parameter("Show Name2", DefaultValue = true)]
        public bool ShowName2 { get; set; }

        public override void Calculate(int index)
        {        
        
            if (!ShowName1)
                return;
            ChartObjects.DrawLine("Line1", ...);
  
            if (!ShowName2)
                return;
            ChartObjects.DrawLine("Line2", ...);                
        }
    }
}
