Create two property groups for class display.

The EmployeeInfo class has five properties describing an employee. Define a getPropertyGroups method that, for scalar objects, defines two PropertyGroup objects. The method returns two property groups with the titles Employee Bio and Contact Info.

classdef EmployeeInfo < matlab.mixin.CustomDisplay
    properties
        Name = "Alex Doe"
        Department = "Development"
        JobTitle = "Engineer"
        Email = "alexdoe@notacompany.org"
        Phone = "(555) 555-555"
    end

    methods (Access = protected)
        function propgrp = getPropertyGroups(obj)
            if ~isscalar(obj)
                propgrp = getPropertyGroups@matlab.mixin.CustomDisplay(obj);
            else
                bioList = ["Name","Department","JobTitle"];
                bioTitle = "Employee Bio";
                bioGrp = matlab.mixin.util.PropertyGroup(bioList,bioTitle);
                contactList = ["Email","Phone"];
                contactTitle = "Contact Info";
                contactGrp = matlab.mixin.util.PropertyGroup(contactList,contactTitle);
                propgrp = [bioGrp,contactGrp];
            end
        end
    end
end

Create a scalar instance to see how the properties are displayed.

a = EmployeeInfo
a = 

  EmployeeInfo with properties:

   Employee Bio
          Name: "Alex Doe"
    Department: "Development"
      JobTitle: "Engineer"

   Contact Info
         Email: "alexdoe@notacompany.org"
         Phone: "(555) 555-555"
