You can set visibility condition on tab(i.e page) based on boolean attribute. Create one boolean attribute ex.‘IsSelected’(or you can use the same attribute that you are using for checkbox).
And set the visibility condition based on the true/false value of the boolean attribute.
Hope this helps you!
You can use the Wizards to achieve your requirement. Style Wizards in Tab style and highlight the respective wizard for the page. So when you go the other it will go to other page but user will get the one page experience.
Another way .
Design one page which will have the tabs and design the tab as per your requirement in one page and place the content on each tab.
Mendix is a one page application so you have to design considering this .
