I’d like a fully-custom mega menu added to the “Projects” tab of my WordPress site. https://lacasacontinua.wpenginepowered.com/ When a visitor hovers over the tab the menu should expand smoothly, reveal multiple columns with room for project thumbnails or icons, and inherit the site’s existing typography and color palette so it feels native rather than an off-the-shelf plugin. https://lacasacontinua.wpenginepowered.com/ Left Side (Product Categories) Location Use this feature for dropdown menus under Products (like “Surfaces,” “Wallpaper,” “Fixtures,” and “Furniture”) and for Projects if applicable. Functionality • When a user hovers over or clicks on a type of product, an image or video automatically appears on the right side of the dropdown — similar to the layout in the reference image. • Each image should correspond to the specific product or room category selected. Surfaces • Marble • Stone • Wood • Porcelain Wallpaper • Vinyl – Vinyl wallpaper • EQ•dekor® – Fiberglass wallpaper • Goldenwall – Metal foil wallpaper • Raw – Rough wallpaper • lineadeko – Multilayer birchwood coverings • Undici – Engraved oak parquet • Tela® system – Backlit textile wallpaper • INK.RUGS® – Printed rugs & moquettes Fixtures • Bathroom • Shower • Kitchen • Accessories Furniture • Collections Please build it with clean, lightweight HTML, CSS and vanilla JavaScript (no page-builder shortcodes). I want it registered as part of my current theme so I can manage items from the standard WordPress Menu screen; no extra admin panels are necessary. The solution must be responsive, keyboard-navigable and follow basic accessibility practices (ARIA roles for menus, focus states, reasonable contrast). please see picture for inspiration
