v6.0.0

v6.0.0 — 2026-07-02

Major release — searchable cascading Country/Town fields, uniform field sizing, searchable job titles

What changed

• Country field is now searchable: covers 90+ countries across Europe, North America, Middle East, Asia, Oceania, Africa, and South America. Customer can type any letter and matching countries appear in a native browser dropdown, or pick from the full list
• Town field cascades from Country: selecting or typing a recognised country automatically repopulates the Town field's suggestions with that country's major cities (e.g. choosing "France" offers Paris, Lyon, Marseille, Toulouse, Nice, Bordeaux, Lille). Town remains free-text, so any city can still be typed even if not suggested
• Job Title field is now searchable too: 40+ common exhibition-relevant titles (Sales Manager, Procurement Manager, CEO / Managing Director, Buyer, Export Manager, etc.) appear as suggestions while typing, but any custom title can still be entered — nothing is locked to the list
• All 5 form fields are now the exact same size: Country and Town were previously native <select> dropdowns which render with different default height/padding than <input> fields in most browsers. All fields are now <input> elements with an explicit height: 44px and identical padding/border/font — guaranteed pixel-uniform regardless of browser
• Implementation uses native HTML5 <datalist> — no extra JavaScript libraries needed, fully accessible, works with keyboard navigation
• Country→city data is defined once in PHP (RHG_Shortcode::country_city_map()) and passed to JavaScript via wp_localize_script, so there's a single source of truth
• Server-side validation unchanged — still simply requires non-empty values, so this works seamlessly with the new free-text-friendly fields
