Programmatically opening Modal form within an opened Slideover does not work.

Description

Hey!

Not sure if this is a bug or a malpractice from my side.

I have my ModalComponent.vue and y SlideOverComponent.vue as separate components that I mould like to open programmatically.

First the user should open the slideover. Then, inside the slideover the user clicks on a button that should trigger the modal to open. However, this does not work, and I wonder why. This works fine when the components are not opened programmatically but with an isOpen value (so in the same file).

Minimal reproduction env: https://stackblitz.com/edit/github-olfzub?file=app.vue

My example code:

• pages/test-page.vue

  
  <script setup lang="ts">
  import { SlideOverComponent } from "#components";
  const modal = useModal();
  </script>

- _SlideOverComponent.vue_
```html
<script setup lang="ts">
import { ModalComponent } from "#components";
const modal = useModal();
</script>

<template>
  <USlideover>
    <UButton label="Open" @click="modal.open(ModalComponent)" />
  </USlideover>
</template>

• ModalComponent.vue

  <template>
  <UModal> OKOK </UModal>
  </template>

Did you correctly add <UModals /> somewhere in your app, preferably in app.vue ?

[francois-duquesne-asl]

Yep. The other modals I open programmatically work just fine.

In my app.vue

<template>
  <div>
    <NuxtLayout>
      <NuxtPage />
    </NuxtLayout>
    <UNotifications />
    <USlideovers />
    <UModals />
  </div>
</template>

Could the order of USlideovers and UModals have an impact?

I am wondering. Could you provide a link to a reproduction ? Could be a z-index conflict maybe, do you know if your modal appears in the dom, or does it log something when being mounted ?

[francois-duquesne-asl]

So, the modal does indeed log something on mounted but seems to disappear just after. When I click on the trigger btn for the modal, the #headlessui-portal-root div (that was present for the sidepanel) disappears. It feels like the new modal is in conflict with the slideover, they both seem to use the #headlessui-portal-root div.

I tried adding prevent-close prop to the USlideover but this did not change the output.

[francois-duquesne-asl]

I do think this is a bug... Can I (or someone) change the label, or should I create a new issue?

[noook]

I labeled it as a bug. If you could provide a minimal reproduction it would be awesome.

Thx! Here is a stackblitz env: https://stackblitz.com/edit/github-olfzub?file=app.vue

I am not too familiar with stackblitz but I did manage to reproduce the bug, hope it works fine for you. 👍

So, to recap:

• ✅ clicking on the "open SlideOver" btn works fine,
• ✅ clicking on the "open Modal" btn works fine.
• ❌ clicking on the "open SlideOver" btn then on the "open Modal" btn inside the slideover is when the bug occurs.

Got the same error if there are two modals on the page, which I open/close programmatically.
