See the following custom control.

My test

using System;  
using System.Windows.Forms;  
  
namespace SplitButtonDemo  
{  
    public partial class Form1 : Form  
    {  
        public Form1()  
        {  
            InitializeComponent();  
        }  
  
        private void firstToolStripMenuItem_Click(object sender, EventArgs e)  
        {  
            MessageBox.Show($@"Hello from {((ToolStripMenuItem)sender).Name}");  
        }  
  
        private void OptionsButton_Click(object sender, EventArgs e)  
        {  
            MessageBox.Show("Clicked");  
        }  
    }  
}
