Steps to reproduce

Create a Nuxt.js project with server-side rendering.

Install radix-vue

Add Accordation component:

Run application with SSR(default)

Observe the issue

• rendered on server: id="radix-vue-collapsible-content-986"
• expected on client: id="radix-vue-collapsible-content-15"

Describe the bug

The ID's generated during server-side rendering differ from those generated on the client during hydration.

• rendered on server: id="radix-vue-collapsible-content-986"
• expected on client: id="radix-vue-collapsible-content-15"

Expected behavior

The server and client IDs should match to prevent hydration mismatches during SSR.

@zernonia useId should not be needed in vue 3.5 if im correct? thanks for your reply

[zernonia]

Technically yes. But internally we are still using interal useId, and requires user to pass in useId function still. Here's a ticket for using newly introduced useId from Vue https://github.com/radix-vue/radix-vue/issues/1267
