Hi Kevin,
Having setup an equivalent product at the test site, I have found the same issue - the textbox group are displaying even though set as hidden.
If you could take a look at the test site and:
At bottom, select WNBook - Add Options
You will see that although the Front Board and the Spine Personal lettering variant groups are hidden, the associted variants still display at the bottom of the product options list.
What should happen is:
select a Size option
select a Standard Colour option
select Edge Gilding option
select the 'Yes Please' at the Spine and Front Board Lettering option
select 'Granby' at the Font Choice option
select a Granby Font Size option
select a Granby Font colour option
select a Number of Granby Characters option
select Where do you want your text
select from the Text Position option
from these options, the Personal Lettering textboxes should then display!
Have I missed anything in the variant group or variant settings please?
Or can you offer any advice as to how I can get his to work?
Your help, as always, much appreciated.
Andrew
