Setting links to open in new tabs is not working

[nocode99]

mkdocs version: 1.0.4
python version: 3.7.0

mkdocs extension:

# Markdown extensions
markdown_extensions:
  - admonition
  - codehilite
  - smarty
  - meta
  - toc:
      permalink: True
  - markdown_include.include:
      base_path: docs

Something like [Title](https://github.com){.new-tab} just renders as Title{.new-tab}

Here is a snippet of the html that is generated:

<p><a href="https://github.com">Title</a>{.new-tab}</p>

I've also tried using {target=_blank} with similar behavior as above.

Attribute lists require that the attr_list extension be enabled. You need to add that to the markdown_extensions config setting:

markdown_extensions:
  - admonition
  - codehilite
  - smarty
  - meta
  - toc:
      permalink: True
  - markdown_include.include:
      base_path: docs
  - attr_list

Thanks! I had trouble finding if an extension was responsible for that. {format=_blank} works but {.new-tab} doesn't but it sounds like this isn't an mkdocs problem anymore.

@nocode99 you mean {target=_blank}.

E.g. the syntax (with - attr_list added to markdown_extensions) is:

To see the example click [here](https://www.example.com){target=_blank}.

I have created the plugin to do that automatically. Plugin opens all outgoing links in new tab.
Look at the plugin: mkdocs-open-in-new-tab.
