I've noticed that since the last Vercel update, some of my sidebar components have stopped working as expected. I haven’t made any changes to the code, and everything appears to function correctly on the deployed sites. However, on the build page, these components are no longer displaying as designed. I’ve attempted to resolve the issue using the prompt, but it hasn’t worked. Could someone please assist?
Can you try deleting your components/ui folder within the v0 preview? (if you have git sync set up, fork first so it doesn't commit it). v0 will work
Ditto. Was working and previewing just fine in builder/preview 6 days ago, made no changes since then, and today (July 2nd), my sidebar navigation component stopped functioning as before and is overlayed on the main window and not fully collapsing. Spent hours trying to fix via prompting and reverting to past forks to no avail!!!
Per the above suggested fix:
Please assist.
Same here.
Sidebar positioned on the left is overlapping with content, and there is no way to fix it by prompting. Have been at it for hours. Very frustrating considering I can't fully see other components. Basically caused me to not be able to continue working on my projects.
Only usable workaround at the moment is to make the menu appear on button click, so you can keep seeing your entire main components - for anyone experiencing the same problem and waiting for a fix.
This happened on all existing projects yesterday, without any changes being made from my end.
Same here!!!
Spent ages trying to resolve. Panicked. Moved my entire project to Cursor.
Ditto. Even when you import the sidebar block directly from https://ui.shadcn.com/blocks/sidebar using the v0 call to action, the layout and sidebar does not have the expected behaviour in a v0 chat. https://v0.dev/chat/sidebar-bug-when-importing-shadcn-to-v0-GbLgltIUwoI
I can reproduce this, I've passed it along to the v0 team internally
Same - this issue only appear in the Preview environment, when published the sidebar behaves correctly. Now do I wait for a fix from v0? I tried rebuilding the sidebar without ShadCN, but ran into a blocker when tooltips also are broken and can't seem to be repaired either in the prototype. It feels like it is part of this bug in the Preview environment.
DItto. I thought this was me but i have spent a HUGE amount of credits with the same problem as you guys with my shadcn sidebar. Have prompted, given examples, screenshots and it just will not fix the sidebar overlapping my content on the page.
I want some of my credits back and a fix because this is holding up my project big time!!
This appears to be an issue with Tailwind 4, we have a fix pending but I don't think it will ship this week
One workaround if your project is hooked up to git sync would be to edit the shadcn sidebar primitive locally and replace it with the latest from the shadcn CLI, which should be Tailwind 4 compatible
I hope this gets fixed soon. I got a lot of stuff with sidebars 
Any eta for the fix?
The team is aiming for this Friday, barring any other blockers along the way
Any updates on this? I’ve been a bit at a standstill on using v0 till I can reliably load sidebars from shadcn.
Hey, is there any update on this?
Yes sidebars work in v0 now
The issue was that v0 was using Tailwind 3 while shadcn components (including sidebar) had been updated to tailwind 4 and some things were incompatible
All new v0 chats use tailwind 4 now and if you have an old one that doesn't work you can ask v0 to update to Tailwind 4 which should fix your sidebars
