An MkDocs plugin that adds tooltips to preview the content of page links using tooltipster

Install the plugin using pip:

pip install mkdocs-tooltipster-links-plugin

Activate the plugin in mkdocs.yml:

plugins:
  - search
  - tooltipster-links

Note: If you have no plugins entry in your config file yet, you'll likely also want to add the search plugin. MkDocs enables it by default if there is no plugins entry set, but now you have to enable it explicitly.

More information about plugins in the MkDocs documentation.

Please reference Tooltipster's getting started guide for additional installation instructions.

Download Tooltipster and add the css and javascript to mkdocs.yml:

extra_css:
  - css/tooltipster.bundle.min.css
extra_javascript:
  - js/tooltipster.bundle.js  

Create custom directory and main.html file for overriding the extra_head template block

mkdir theme
touch theme/main.html

Add the following to main.html:

{% extends "base.html" %}
{% block extrahead %}
        <script src="https://ajax.googleapis.com/ajax/libs/jquery/3.4.1/jquery.min.js"></script>
        <script>
                $(document).ready(function() {
                    $('.link-tooltip').tooltipster();
                });
        </script>
{% endblock %}

Add the custom directory to mkdocs.yml:

theme:
  name: mkdocs
  custom_dir: theme

Add additonal css to the site (either in a new css file or existing one):

.tooltip_templates { display: none; }

Once configured property, tooltips-links should create tooltips automagically!
