Is there a way to do it. e.g.
1st Jan
- 8am - 9am
- 9am - 10am
3rd Jan
- 8am - 9am
- 9am - 10am
So users can select either 1st Jan or 3rd Jan and then select the timings within. Please do not take this question down even though I accept it is a repeat (https://sharepoint.stackexchange.com/questions/57580/how-to-create-a-survey-in-sharepoint-which-supports-sub-options-in-choice-item). No answers/comments were given on that question but I hope this post is replied to even in the negative.
