I am planning to create a checklist using the checkbox group for each users seperately. I have created the page in member pages and added a checkbox group.
I need the checked boxes to be the unchanged ( currently once I refresh all boxes unchecks) even when the user refreshes or logs out and login again.
The checklist of a member should not disturb the other members checklist. Please advise.
What you need is to have the checkboxes in a form with a submit button so that the member can submit their chosen options into a dataset collection.
Then you will need to get the info from your dataset and set the checkbox values on your page.

If you are keeping it all on the same [age, then you are probably going to need to refresh the dataset after the user inputs are submitted and saved. Plus you will probably have to refresh the page too so that the page can then read the new values from the dataset.
