Slot for top or bottom of document

[ronaldaug]

Is your feature request related to a problem? Please describe.

According to the documentation, it seems there is no slot like before or after document content.

I just want to add global components such as search box or breadcrumbs on top of every document.

There is an option that I can add <bread-crumbs /> to every .md documents. However, I think this is not a proper way to do it as it's used in every documents.

Describe the solution you'd like

Adding a slot before or after the document content.

<template #doc-before></template>
<template #doc-after></template>
