Class Summary HTML_Menu_SigmaTreeRenderer

Class Summary HTML_Menu_SigmaTreeRendererHTML_Template_Sigma-based renderer for 'tree' and 'sitemap' type menus, where menu level is represented by tag nesting.


The renderer generates outpu similar to that of HTML_Menu_DirectTreeRenderer but offers more possibilites for output customization.

The renderer may also work with HTML_Template_IT instance, but as menu templates tend to have lots of blocks, HTML_Template_Sigma's cache feature will give a significant performance improvement.

Template structure

This is the minimal template for HTML_Menu_SigmaTreeRenderer, containing all the required blocks:

<!-- BEGIN mu_tree_loop -->
    <!-- BEGIN mu_level_open -->
    <!-- END mu_level_open -->
        <!-- BEGIN mu_entry_open -->
        <!-- END mu_entry_open -->
        <!-- BEGIN mu_active -->
        <!-- END mu_active -->
        <!-- BEGIN mu_inactive -->
    <a href="{mu_url}">{mu_title}</a>
        <!-- END mu_inactive -->
        <!-- BEGIN mu_activepath -->
    <a href="{mu_url}"><em>{mu_title}</em></a>
        <!-- END mu_activepath -->
        <!-- BEGIN mu_entry_close -->
        <!-- END mu_entry_close -->
    <!-- BEGIN mu_level_close -->
    <!-- END mu_level_close -->
<!-- END mu_tree_loop -->

A more complete example showing possible customizations can be found in the package archive.

Note that blocks and placeholders in the template have mu_ prefix. This is done to prevent name conflicts with existing blocks and placeholders, mu_ is the default prefix, another prefix can be passed to class constructor.


This block should always be present and should be a parent for all other blocks. It is used to implement "flow", to render entries one after another.

level_open, level_close

These blocks will be used on start and end of each menu level. If level-specific blocks %level%_level_open and %level%_level_close are present, they will be used instead.

entry_open, entry_close

These blocks will be used on start and end of each menu entry. If level-specific blocks %level%_entry_open and %level%_entry_close are present, they will be used instead.

inactive, active, activepath

These blocks are used to output menu entries, they correspond to possible entry types. Each block should contain a {title} placeholder and may also contain {url} placeholder. As usual, if other keys are present in original menu array they will be assigned to corresponding placeholders in the template.

If level-specific block %level%_%entry type% exists, it will be used instead.
