Thanks so much for your kind help always Greg.

I'm afraid dropdown lists is not a good choice for me and it would be less user-friendly having too many option buttons in my docs.

I noticed that only my docs that have many option buttons (ActiveX Controls) are too slow to open and I was hoping I could have a macro to be able to use checkboxes instead and I came across your good article (linked below) but I'm afraid it only applies to Word 2010 and above as far as I understand so far from reading it ! I hope I'm wrong about this
