    Thank you for this great work.

    I have checked the form and the codes you are using on it, I have to say it works perfectly, I did what you say in the description, deleted an LI option and I can see the change in the form.

    I will bookmark it, could help us in the future in post related to this.

    One more time, thank you for share us this.
