==> Tell us what you are trying to do?
NEGOCIOS (businesses) custom post type have 5 main business types (mean that some of the mainly - Field Groups, will be separated, depending of business type, but front-end/single.php will be essentially the same). Accommodation specifics are mostly Rooms (with services, beds, ...), Gastronomy are mostly Menu (ingredients, services, ...), Services are mainly generalized Services, Shopping is manly Products and Mixed are Mixed.
Initial concept (idea) was to use 'nested repeatable groups' (NRG), but it looks that I should completely to switch to Types 2 as I found also some other issues (BUGS) related to 'repeaters'. Downgrade also bring lot of the problems as checkboxes are not available for conditional logic, what all lead to HUGE AMOUNT of 'nested child posts'. I have opened other tickets with essentially connected issues.
PROBLEM
Main problem in concept starts from real life situations that lot of the businesses are 'mixed'. Examples - Hotels with restaurants, Paper store (shopping) with services (copy), to not go further. There is also other type of 'mix' - several locations (ie - restaurants). Finally, 'combined mix' (both), as well.
I actually created 'raw' fields and now I should to start 'distribution'. Some should be changed depending of concept (selection to checkboxes - ie). I get vary simple idea how to do it easy with NRG, but it looks that I must to forgot for it. Now, I should to start to create all those (very simple/basic) custom post types (mostly with one field) and to 'chain' it (nest it), but contrary (to place it as parents, while NRG are nested as child's).
DILEMMA
1) NRG are also CPT (hidden). However, too many 'regular' ('chained') CPT will make the problem for site/page loads (and/or search) performances or not?
2) Main (business) CPT Content Template will 'suffer' from (ie) 10 'levels' of 'nested' post types (or not)?
Example (5 levels deep) - Negocio (Main = Content Template) > Hotel + Restaurant (2 secondary child CPT) > Rooms > Beds > Seasons (Prices)
3) How to display some mix? I thought to use Tabs, but I can't see that it is supported by Layouts and Content Templates. Is it?
