How to insert elective subjects section within a diagram

Question

This is and addendum of the "Ingredients" section posted on a previous question: How to draw a diagram of custom subject correlativities.

We need two more ingredients:

Make an elective subject. We can label it as nonfillable elective subject:

Also, we need to have a fillable elective subject, called for example fillable elective subject:

As said in the question, you can use this very helpful answer.
Make a shape that contains a set of elective subjects:

(Both the background color of the shape and the TextField's may vary. Do not worry about that).

What I need

The last shape must be in the lower part of the big orange rectangle, without reaching all margins.
The elective subjects can have different heights depending on the stack of elective subjects but the width is always the same, but the elective subjects inside it must be centered:
Note that elective subjects do not relate to any object, so that's why we can reduce the width of the light blue shape.

What I have done

The same source code of marmot's answer:

I think that we could also use the matrix command of the TikZ package to position the pictures inside the light blue shape, but we need to define a new type of subject: (non)fillable elective subject.

Final result

Similar to the original question but adding these new shapes and vertically centering those subjects that are between "Level X" and the light blue shapes:

Thanks!!

If you dont mind, could you please add the code from the linked questions (I would still retain the links :)). So that it will be easier for looking-up. — Raaja_is_at_topanswers.xyz, Mar 13 '19 at 10:59

Here is an answer for your updated question. (To those who feel I shouldn't add two answers: I will be happy to remove one of them. However, I think that the other one might be potentially useful for others.) As before, the strategy is to write computed distances to the aux file such that they can be used after a recompilation.

(I understand what this code does... but I'm not sure that I understand what it tries to do. ;-)) — Paul Gaborit, Mar 19 '19 at 06:27
@PaulGaborit It tries to collect the dimensions of all nodes in the first run and then use the information to place the nodes in the second run, doing what in ordinary LaTeX \hfill and \vfill do. AFAIK there are no TikZ analogs of \hfill and \vfill. Of course, in less complex examples you do not need them, but here I didn't see a way to accomplish the task with the ordinary positioning library. — , Mar 19 '19 at 06:32

The main complication is that one cannot yet (?) nest tikz matrices. So this proposal follows a slightly different strategy, which is conceptually more or less the same as the one used here:

Build the matrices with some guessed distances.
Measure the matrices.
Compute "optimal" distances from the measured values.
Write the "optimal" distances to the aux file such that they can be used after recompilation.

The example has a lot of annotations that should help to understand what is going on. Notice also that you have to loop over the actual inlays, that is, if you want to add or remove inlays, you may have to modify \foreach \X in {0,2,3}.

Yes of course, I agree with your answer. No problem in compiling twice. — manooooh, Mar 14 '19 at 17:24
@manooooh I updated my answer. Notice that it is quite possible that there is a simple trick that allows one to avoid this gymnastics but everything I could come up with (like putting the matrices into a tabular) is of comparable complexity, or even more complex. — , Mar 15 '19 at 00:33
