Thanks for checking it out and for your feedback. Keep up the great work, guys!

Hi,

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.

Regards.
