for some reason it changing button inside DropdownMenuTrigger and it breaks.
you have couple such occurrences in Sidebar.js and Navbar.js
you better use shadcn button instead default one like this:

import { Button } from "@/components/ui/button"

like in example on their site https://ui.shadcn.com/docs/components/dropdown-menu

Thank you so much

but why it's still hydration after i fix it

should be fine, can you update repo on github

oki i did

add asChild to DropdownMenuTrigger like from shadcn example

also in LargeCard.js you have (item.sale).toLocaleString() which breaks hydration
you either need to offload it to useEffect, either change somehow different, because througout hydration it don't have locale, so data will be different.

not to closing one, to opening one

oh i see my badd

i did add asChild but

how to avoid this err

you missed something, for me after adding asChild all <button> errors missing

what should i do

Can you help me pls

hmm, it show me error again, now I will try to download repo again and fix it.

what about i streaming my screen on discord is that ok if u dont mind can i invite u to my discord

it will take more time like this, easier if I'll test it myself.

oki thank u so much

yeah
you need to add asChild to DropdownMenuTrigger at Navbar.js and Sidebar.js
you have 3 such elements, so 2 at Navbar, 1 at Sidebar

but in Sidebar.js you have {" "}<Button..... so it's 2 elements, but asChild allow one only, so you either need to remove {" "} but if you need it, you need to wrap this to elements to react fragment <></> like on screenshot:

it's workkkk thank you so much
