Using a custom Portal component

Use Version
Use version when question appear:

• Headless UI: v1.7.7
• Headless UI Float: v0.10.1
• Framework: [vue v3.2.33]

Describe the question
I'm trying to render a HeadlessUI Combobox inside a Popover. For this, I need to teleport the combobox options to the body, so that the dropdown options can overflow the popover, and the popover won't show scrollbars.

However, there's an issue - when clicking any of the combobox options, the popover is immediately closed. I believe it is because of the click outside handler, which now sees the options as being rendered outside of the popover. I saw a mention in HeadlessUI repo that using the Portal from @headlessui/vue instead of the regular Teleport component should help with this. Unfortunately, I don't see that it's possible to customize the portal component for Float. Would you consider supporting something like that? Or perhaps there's another solution to the issue?

Hi @ragulka, can you provide a minimal reproducible question example (like github repo, codesandbox, stackblitz...) for me to debug 😅? I will refer to your suggestion and try to find a solution.

Hi @ragulka, I think this can be broken down into two parts.

First, regarding the change of Teleport to use the <Portal> component of Headless UI, I have already modified it and released it to v0.11, thank you for your reminder.

Second, if you want to use Popover and Combobox, you don’t need to use the portal, here is an example for you to test:

<template>
  <Popover v-slot="{ close }">
    <Float
      placement="bottom-start"
      :offset="15"
      :shift="6"
      :flip="10"
      arrow
      enter="transition duration-200 ease-out"
      enter-from="opacity-0 -translate-y-1"
      enter-to="opacity-100 translate-y-0"
      leave="transition duration-150 ease-in"
      leave-from="opacity-100 translate-y-0"
      leave-to="opacity-0 -translate-y-1"
    >
      <PopoverButton class="px-3 py-1.5 flex justify-center items-center bg-rose-50 hover:bg-rose-100 text-rose-500 rounded">
        Open
      </PopoverButton>

      <PopoverPanel class="w-[240px] bg-white border border-gray-200 rounded-md shadow-lg focus:outline-none">
        <FloatArrow class="absolute bg-white w-5 h-5 rotate-45 border border-gray-200" />

        <div class="relative p-3 bg-white rounded-md">
          <label class="inline-block mb-1">Combobox</label>
          <Combobox v-model="selected">
            <Float
              as="div"
              class="relative"
              placement="bottom-start"
              :offset="4"
              leave="transition ease-in duration-100"
              leave-from="opacity-100"
              leave-to="opacity-0"
              floating-as="template"
              @hide="query = ''"
            >
              <div class="relative w-full text-left bg-white border border-gray-200 rounded-lg shadow-md cursor-default focus:outline-none sm:text-sm overflow-hidden">

                  @change="query = $event.target.value"
                />

              </div>
