Default theme's smooth scrolling feature not working

[wallslide]

• I confirm that this is an issue rather than a question.

Bug report

Steps to reproduce

Here is the link to the repository with the issue --> https://github.com/appsocially/upil-site
The corresponding vuepress site is at https://upil.org/

I added the smoothScroll option to config.js here as is detailed in the docs.

What is expected?

Clicking links on the sidebar that point to the current page should smoothly scroll the page to that section.

What is actually happening?

The page jumps to intra-page anchors instead of smoothly scrolling to them.

Hi @wallslide,

Actually smoothScroll feature was not released yet... It will be available in the next version of VuePress.

Our doc is always in bit ahead of releases 😅We need to fix this.

HHH I found this question ,too.

Maybe you can release a website called beta-vuepress.vuejs.com and merge your ahead Doc changes when new version released?

@Mister-Hope I described something that might be the solution here

[wallslide]

When I searched for related issues first, I found this one #567 and saw that it resulted in a merged pr, so I got thrown off by that :)

@kefranabg We can let each new feature have a compatibility badge, e.g.

• input:

# Content <Badge text="1.0.0+" />

• output:

Maybe it should be listed in the contribution guide and pull request template.

@ulivz I think using badge is a good idea to solve this 👍
