function phptemplate_links in Power Menu 6

Same name and namespace in other branches

1. 7 power_menu.module \phptemplate_links()

Return a themed set of links.

The important difference is that we use the in_active_trail bit here to set an "active" CSS class, which is what most themes (e.g. garland) use to denote an active/open menu item. You should alter/override this as your design needs dictate.

Parameters

$links: A keyed array of links to be themed.

$attributes: A keyed array of attributes

Return value

A string containing an unordered list of links.

File

./power_menu.module, line 439

This module provides some additional menu features. The features are not actually new, but are part of other modules. it's though very cumbersome to creating a new menu item, because one has to go to all the different places to configure these…
