I intend to create sub-sections within sections. That is, I want to have three tabs – Soils, Copernicus, and Bioclimatology (which would be the main sections). Then, within the Copernicus section, I want to have sub-sections such as Thermal Index, Coarse Fragments, and Soil Erosion (among others). When clicking on a sub-section, for example, the Thermal Index, the corresponding map should appear.
I can display the Thermal Index and its map, but I am unable to place the Thermal Index within the Copernicus section. How can I solve this issue?
I would like something similar to the following website:

Could you provide guidance on how to fix this?
