Dropdown with click outside pattern

What would be the best pattern to create a dropdown menu div or menu div with an onClick handler outside to auto close it? not a hover menu, mind you, but a click menu. I know how to show it, but I recall handling the onClick outside of the element actually implied something like portals or annoying dom manipulation in react, and I'm wondering if solid (or some community-made primitive) has a better idiomatic pattern for this? Currently my component looks like

export const FilteringDropdown = (props) => {
  const [isShown, setIsShown] = createSignal(false)
  return (
    <div class="relative">
      <button class="border-0 bg-transparent cursor-pointer m-0 p-2 whitespace-nowrap" onClick={() => setIsShown(!isShown())}>
        <span class={`px-2 h-[24px] w-[24px] ${props.icon}`}></span>
        {props.title}
        <span class="h-[24px] w-[24px] i-material-symbols-keyboard-arrow-down"></span>
      </button>
      {isShown() && <div class="absolute top-10 left-0 w-lg bg-white border-1">FILTERS!</div>}
    </div>
  )
}

export const FilteringDropdown = (props) => {
  const [isShown, setIsShown] = createSignal(false)
  return (
    <div class="relative">
      <button class="border-0 bg-transparent cursor-pointer m-0 p-2 whitespace-nowrap" onClick={() => setIsShown(!isShown())}>
        <span class={`px-2 h-[24px] w-[24px] ${props.icon}`}></span>
        {props.title}
        <span class="h-[24px] w-[24px] i-material-symbols-keyboard-arrow-down"></span>
      </button>
      {isShown() && <div class="absolute top-10 left-0 w-lg bg-white border-1">FILTERS!</div>}
    </div>
  )
}

obviously, it only opens or close on clicking the button.

solid-headless has a menu component that works based on focus. menu is open as long as it has focus. you click outside, it losses focus. There is solid-dismiss as well

I keep being reminded that I should start using solid-primitives to the same extent I use lodash dogkek

yeah it's always a fine balance, at one point, you reach the threshold of "well I really should use that library even if it means I'll have to rewrite a few patterns"

same with lodash when I finally gave in and used it for my enmap module - suddenly 100 lines of code changed because it was better to use isNil and isObject and isFunction everywhere since I was using get() anyway I haven't reached the threshold yet. I'm going to use solid-dismiss for now

the problem I have with this kind of implementation is that when it comes to nesting, it breaks immediately. Sure it works for simple cases
