As one does these days, I pointed some coding agents to this task and they added the missing components. This PR adds comprehensive documentation and examples for 30 missing shadcn components, achieving 100% feature parity with shadcn-ui. The work includes complete MDX documentation,
interactive examples, bug fixes, and code formatting improvements.

Bug Fixes

Critical Fixes

• 🐛 Badge - Fixed missing as="span" prop for Polymorphic component

  • Error: [kobalte]: Polymorphic is missing the required 'as' prop
  • Solution: Added default as="span" to Badge component

• 🐛 Scroll Area - Fixed scrollbar thumb not reaching bottom when scrolled

  • Issue: Scrollbar used flexbox + transform positioning
  • Solution: Changed to absolute positioning with top and height properties
  • Result: Scrollbar now accurately reaches 100% when scrolled to bottom

• 🐛 Calendar - Fixed heading not displaying month/year in DatePicker context

  • Issue: Show fallback evaluated statically instead of reactively
  • Solution: Changed to reactive function using CalendarPrimitive.useContext()
  • Result: Month/year displays correctly in both standalone and portal contexts

Enhancements

• 🔧 Sheet - Added showCloseButton prop (defaults to true)
  • Allows hiding the close button when needed

Statistics

• Files Changed: 108 files
• Insertions: 11,250+ lines

• Registry Items: 164 total (up from ~110)

Technical Details

Component Architecture

Code Quality

• ✅ Registry Rebuild - All components registered correctly
• ✅ Manual Testing - All components tested for functionality

File Structure

└── config/docs.ts # Navigation updated

Testing

All components have been manually tested:

• ✅ Component rendering
• ✅ Interactive functionality (tabs switching, sheets opening, forms submitting)
• ✅ Accessibility (keyboard navigation, ARIA attributes via Kobalte)
• ✅ Responsive behavior (mobile sheets, collapsible sidebar)
• ✅ Examples match documentation
• ✅ No console errors or warnings

Specific Test Cases Verified

• Tabs - Tab switching works correctly (fixed defaultValue issue)
• Sheet - All 4 sides (top, right, bottom, left) slide correctly
• Separator - Visual alignment in vertical and horizontal modes
• Sidebar - Collapses to icon mode, stays within preview container
• Data Table - Sorting, filtering, pagination, row selection all functional
• Date Picker - Calendar popup, date selection, placeholder text display
• Scroll Area - Scrollbar reaches bottom correctly (post-fix)

Migration Guide for Users

Users can now install any of these 30 components using the CLI:

# Install individual components
npx @solid-ui/cli add calendar
npx @solid-ui/cli add chart
npx @solid-ui/cli add data-table
npx @solid-ui/cli add date-picker
# ... etc for all 30 components

All components follow the same installation and usage patterns as existing solid-ui components.
