I'm looking for the best approach to this problem.

In my tableview I have a list of options from which you can select one and only one. The problem is the selection to choose is not obvious without displaying more details on the option.

If I use the disclosure indicator or button for the more detail, I lose the checkmark functionality.

In searching around I see some have used the cell Image as a work around. I see others instead of using the standard disclosure button have created custom disclosure button looking like a checkmark. Haven't seen this one but is it viable (HIG) to add a button in the cell ('more info') to launch the next tableview.

My thought was to use a disclosure indicator and on the second view in the navigation bar (where the edit button usually is) add a 'selectMe' button.

I think I am probably manage to code either of the above, am just asking for information on what is the best (HIG) way.

Example

Option 1
Option 2 Option 3 (x) Option 4

Where x is the checked one

But in order to know which is the best choice you need to see

Option 3 (Header)

Option 3-a Option 3-b Option 3-c > Option 3-d

Where even at this level option 3-c might have additional information.

Any guidance you can provide would appreciated.
