I also want to add that when using indicator <NavigationMenuIndicator /> (before NavigationMenuList closing tag), it translates back to the first link when closing the popover of other menu items, which looks very weird and buggy.

And when using :disable-hover-trigger="true" it sometimes closes on mouseout and sometimes it stays open. Why this prop is not disabling trigger hover events all together instead of some unexpected mixed behaviour?

@ZTL-UwU My menu has some custom tweaks, so I am not sure this will work if you use example from the docs.

Try this: Go to NavigationMenu.vue component and instead of max-w-max put w-full on NavigationMenuRoot class

Then it should auto-position the dropdown, only drawback is that dropdown can't have bigger width than the NavigationMenuRoot div.

Edit: this is my class for the root: relative z-10 flex w-full items-center justify-center with this class list the dropdown will be centered inside this container and not at the start.

So, this indicator translate happens because of how tailwind-animate classes animate-in and animate-out work; they add animations for several properties, including transform/translate.

So if someone is using indicator:

<NavigationMenu>
  <NavigationMenuList>
    <NavigationMenuItem>
      <NavigationMenuLink>...</NavigationMenuLink>
    </NavigationMenuItem>
  <NavigationMenuIndicator />
  </NavigationMenuList>
</NavigationMenu>

If you just want to fade the indicator (without translating it to the initial state), replace all [state-hidden] and [state-visible] classes with this: data-[state=hidden]:animate-fade-out data-[state=visible]:animate-fade-in

And fade-in and fade-out is already defined in tailwind.config.js as part of shadcn. I just like to adjust it to my custom settings:

animation: ({ theme }) => ({
  // Other animations...
  "fade-in": `fade-in ${theme("transitionDuration.DEFAULT")} ${theme("transitionTimingFunction.DEFAULT")}`,
  "fade-out": `fade-out ${theme("transitionDuration.DEFAULT")} ${theme("transitionTimingFunction.DEFAULT")}`,
}),

@ZTL-UwU This is long standing issue in radix-ui and radix-vue

This should be fixed in radix-vue v2
