I've created a comprehensive menu editing page that matches the requirements from your text and follows the design aesthetic of the provided image. The interface includes all requested modules: menu information with form fields, effective information with checkboxes and time selectors, associated dishes section, and a two-column layout for categories and dishes. The left category list is clickable to filter the right-side dish list, and I've included proper state management for all interactive elements. The design uses a clean, professional layout with shadcn/ui components and maintains good spacing and visual hierarchy.
I've restructured the layout to minimize the configuration sections and maximize the menu items area. The configuration sections (menu information, effective information, and associated dishes) are now arranged in a compact 3-column grid at the top with smaller form elements and reduced spacing. The menu items area below has been enlarged with a minimum height of 600px and uses flexbox to fill available vertical space, making the tables more prominent and easier to work with.
