Custom Multi-Step Directory/Listing Pages for WordPress (No Elementor) Project Overview We need a custom-coded listing directory for praguemorning.cz. The goal is a 3-step navigation flow that allows users to drill down from broad categories to specific listings. Strict Requirement: No Page Builders (Elementor/Divi). We want lightweight, clean code (Gutenberg blocks, ACF, or a custom PHP template) to ensure fast loading speeds. Navigation Flow Level 1 (Main Hub): A page featuring 3 large, clickable image tiles: Food, Health, and Education. Level 2 (Subcategories): Clicking a main category opens a similar grid of subcategories. Example: Food → Pizza, Burgers, Sushi. Example: Health → Dentists, Clinics, Pharmacies. Level 3 (Final Listings): Clicking a subcategory opens the final archive page containing the full list of business listings/clients for that specific niche (like this one: https://www.berlinfoodstories.com/top-lists/the-best-burger-in-berlin) Design: Must be clean, modern, and integrate seamlessly with the current Prague Morning aesthetic. Easy-to-use backend (ACF or similar) so we can add new categories/images ourselves.
