Pico Pages List

A flat and nested pages lists plugin for Pico CMS.

• {{ nested_pages }} array
• nested or flat html navigations
• pages links and directories structures
• versatile html/css for dropdown menus, single-line breadcrumbs...
• exclude and only pages filters

Demo : http://pico.nliautaud.fr/PicoPagesList

Installation

Copy PicoPagesList.php to the plugins directory of your Pico Project.

Usage

Create a nested HTML navigation tree with :

{{ nested_pages | navigation }}

The nested navigation will look like that :

• A cool page
• Sub-page is coming
  • The choosen one
  • category
    • A page
• untitled

The global nested_pages and the filter navigation render an HTML navigation. Works on {{ pages }} too.

{{ pages | navigation }} // output a flat pages list

Filtering

The plugin create two additionnal Twig filters, exclude() and only(), that filters the given pages array (pages or nested_pages) by paths.

pages | exclude('path/')    // exclude the page located under "path/"
pages | only('path/')       // return only the page located at "path/"

Use the leading slath to target index pages or not.

pages | exclude('sub/dir/')     // exclude the page located under "sub/dir/", but not "sub/dir" (index)
pages | exclude('sub/dir')      // exclude "sub/dir" (index) and pages located under "sub/dir/"

You can specify multiple paths at once by using multiple arguments.

exclude('sub/dir', 'page')
only('sub/dir', 'page')

Styling

The default html output is a clean nested list with extra classes that provides the possibility to build hierarchical navigations and to target specific pages and directories.

<ul>
  <li class="titled is-page">
    <a href="http://mysite.com/titled">A cool page</a>
  </li>
  <li class="foo is-page has-childs is-current">
    <a href="http://mysite.com/foo">Sub-page is coming</a>
    <ul>
      <li class="child is-page has-childs is-current is-active">
        <a href="http://mysite.com/foo/child">The choosen one</a>
      </li>
      <li class="category is-directory has-childs">
        <span>category</span>
        <ul>
          <li class="bar is-page">
            <a href="http://mysite.com/foo/category/bar">A page</a>
          </li>
        </ul>
      </li>
    </ul>
  </li>
  <li class="untitled is-page">
    <a href="http://mysite.com/untitled">untitled</a>
  </li>
</ul>

.foo-item { /* an item named "foo-item" */ }
.foo-item > a { /* the link of a page named "foo-item" */ }
.foo-item > span { /* the name of a directory named "foo-item"  */ }
.foo-item > ul { /* the childs of "foo-item" */ }
.foo-item > ul ul { /* the deep childs of "foo-item" */ }

.is-page { /* the pages, with links */ }
.is-directory { /* the directories, with simple names */ }
.is-current { /* the current page */ }
.is-active { /* the items in the path of the current page */ }
.has-childs { /* the items with childs */ }

As a simple example, you may show sub-pages only if their parent is active :

.mymenu li.is-page:not(.is-active) ul {
    display: none;
}

Custom loop

The {{ nested_pages }} global is an array of pages, similar to {{ pages }}, where sub-pages are nested into _childs.

You may want a recursive Twig template or macro to walk trough it, for example :

{% macro menu(items) %}
  <ul>
  {% for name,item in items %}
    <li>
      {% if item.url %}
        <a href="{{ item.url }}">{{ item.title }}</a> : {{ item.description }}
      {% else %}
        <span>{{ name }}</span>
      {% endif %}
      {% if item._childs %}
        {% import _self as macros %}
        {{ macros.menu(item._childs) }}
      {% endif %}
    </li>
  {% endfor %}
  </ul>
{% endmacro %}

{% import _self as macros %}
{{ macros.menu(nested_pages) }}

Settings

The lists are sorted according to the default settings in Pico config.php.
