Hmm - I am not seeing that. When I click RELAX I don't have any alternative choices, and the timetable doesn't appear below the orange bars. The orange bars show the 6 blocks, but only the Options, not the LS/Sport. Looking at student timetables, I can see the LS/Sport at the times scheduled in NT6 - but I can't switch these times (and in any case, if I was to drag a "LS" to a different slot, could I then replace it with the option class??). E.g. Geography is shown as Day2 Period 7 but should be Sport. Sport shows as Day3 Period 2. If I could drag Sport from D3:P2 to D2:p7, could I then drag Geography to D3:P2?
I suspect this structure might be difficult to model, as there is a pre-determined LifeSkills/Sport timetable, and the Core/Options timetable fits on top.
In other words, a student in block1 (let's say, Geography is his block 1 choice) takes 2 periods of Lifeskills at any 2 of 6 periods, and a period of sport at any 1 of 4 periods. Another student in block 1 is taking IT, but takes his 3 periods at different times to the first student. Sorry if this is unclear: if you like I can try to send some more graphics?
Thanks again for the advice so far.
