Gooday to everyone.
I've prepared a long survey with mandatory and not mandatory questions.
I would like to let participants of the survey to freely move between the different question groups also if they have mandatory question, but have not the possibility to confirm and submit the survey if they have not complete all mandatory questions.
For the moment thay will face a group after the other, following the structural order. I woul like they could move following the index, in the group they could answer in that moment, than save the survey, collect info about others groups and go back to it and repeat the cicle.
Could someone help me?
Is that possible without using java script?
Thank you.

Did you activate the full index ?
Is done for this.

Yes, but from it you can't move to others groups 'cause of the mandatory questions..
I can see the full index I can click on the group I want to reach but than comes the error: there are some mandatory question not answered, and i can't move..
so I wuold like to know if i can bypass that, but not permit to submit the survey without complete all questions..

Waht version ?

And you choose full index ?

Because with full index : you can always move to any relevant group …

this is the version i'm using 3.17.7+190627.
i've attached a picture where you can see that i've choose the full index.
if i've not completed a question group (i'm using groups visualization), and than i try to move to another i can't 'cause of the mandatory questions..

Maybe an issue with Ajax mode in Theme (i always disable it globally).

FANTASTIC!!!! I've disabled Ajax mode and now everything work properly!
thank you so much!
