Here is an implementation of a basic tag browser that allows users to filter content based on multiple criteria.

Note that you’ll also want to implement the crawler mitigations.

First, you’ll need to modify your content view with tag_filter='ALL'; for example, at the top of your template, have a line like:

index.html
{%- set view = view(tag_filter='ALL') -%}

Next, this block will give you a tag filter that shows the top 10 tags present in the current view in addition to any tags that are currently selected, with a toggle to show all tags that have more than one entry:

{%- if not user.is_bot and category.tags(recurse=view.spec.recurse) -%}
<div id="tags"><h3>Topic Tags</h3>

    {% macro tag_link(view) -%}
    {{view.link(template=template,all_tags=1 if request.args.all_tags else None)}}
    {%- endmacro %}

    <ul>
        {%- if view.tags -%}
        <li class="clear"><a href="{{tag_link(view(tag=None))}}">Clear filter</a></li>
        {% endif %}

        {% set tags = category.tags(tag=view.spec.tag if view.spec.tag else None,
            tag_filter='ALL',recurse=view.spec.recurse)
            | sort(attribute='count',reverse=True) %}
        {% for name,count in (tags if request.args.all_tags else tags[:10+view.tags|length]) %}
            {%- if count > 1 and
                (request.args.all_tags or loop.index < 10 or name in view.tags) -%}
                <li class="{{name in view.tags and 'selected' or ''}}"><a rel="nofollow" href="{{tag_link(view.tag_toggle(name))}}">{{name}}</a> ({{count}})</li>
            {%- endif -%}
        {% endfor %}

    {% if request.args.all_tags %}
        <li class="top-only"><a rel="nofollow" href="{{view.link(template=template)}}">Top tags only</a></li>
    {% elif tags|length > 10 %}
        <li class="all"><a rel="nofollow" href="{{view.link(template=template,all_tags=1)}}">Show all tags</a></li>
    {% endif %}
    </ul>
</div>
{% endif %}

This stylesheet snippet will add useful styling to the tag list, as well:

#tags ul {
    list-style-type: none;
}
#tags li {
    text-indent: 1em hanging;
}
#tags li:before {
    content: '☐\00a0';
}

#tags li.clear:before {
    content: '☒\00a0';
    font-weight: bold;
}

#tags li.selected:before {
    content: '☑︎\00a0';
}

#tags li.all, #tags li.top-only {
    font-style: italic;
}
#tags li.all:before, #tags li.top-only:before {
    content: '';
}
