Example page is quite... repetitive

Request 1:

Link: https://mapdl.docs.pyansys.com/version/stable/examples/index.html

The side navigation bars are very similar:

I would remove one.

Request 2:

Ideally, on the left bar, we should not see each of the examples. They should be grouped in Extended examples. Like:

Section Navigation
 - Full examples using PyMAPDL
 - PyMAPDL math examples
 - Geometry examples
 - Miscellaneous examples
 - Academic finite element examples
 - Verification Manual
 - Technology Showcases
 - Extended examples
    + Cart-Pole Simulation
    + Gmsh example
    + UPF in PyMAPDL
    + Harmonic analysis using the frequency-sweep Krylov method
    + Use Dash to build a PyMAPDL web app
    + Create your own Python command-line app

Similar to the gallery examples.

I cannot find a way to hide "On this page" nav bar for a single page. Pinging @Revathyvenugopal162 and @jorgepiloto for input.

Assigning this to @Revathyvenugopal162 and @jorgepiloto because this seems to be too much for me. I have tried for quite a lot of time and I cannot come up with a good solution
