Hello, I have tables:

spech_teches - it has special equipment - title, description, image, category_id

categories - categories of techniques, it has -title, image

and also has child tables:

categories_options - these are the types of characteristics of a certain category of equipment, it has - title, category_id

spech_teches_options - these are the characteristics of a particular technique, the types of characteristics depend on the category of the technique itself, it has - title, value

so this is how to link tables with child tables using EloquentORM)
