#Pro Menus plugin for Croogo

Pro Menus enhances Croogo's menu system in the following ways:

• Adds a textarea to the add/edit links admin pages where you can enter PHP code that determines if the link is selected
• Provides a way to specify which level of links you want displayed and the number of sub-levels required
• Includes a helper method to display a breadcrumb
• Adds a 'selected_trail' class for parent links of the selected link
• Optionally adds 'first' and 'last' classes

##Examples & Usage

###PHP code for determining selected state * ** Click on the 'Pro' tab of the add/edit link page and enter PHP code. You have access to params via $this->params. Example: entering return $this->params['plugin'] == 'gallery'; will keep the link selected for every controller/action combo of the gallery plugin

* SECURITY WARNING: This uses a simple eval() of whatever is entered into the textarea. Some kind of sandbox has to be built. Suggestions welcome.

** Only works if you are using the Pro Menus Helper.

###Pro Menus Helper The Pro Menus Helper provides a replacement for the Layout Helper's menu method and a way to display a breadcrumb.

####Displaying a menu Use the Pro Menus Helper's menu method instead of $this->Layout->menu():

• $this->ProMenus->menu('main', array('sub_levels' => 2)) will display the first level, and two sub levels
• $this->ProMenus->menu('main', array('for_level' => 1, 'sub_levels' => 1)) will display the child links of whichever first level link is selected or is part of the selected trail, and the next sub level

#####Options

Option	Values	Default	Description
for_level	int	0	specifies the level of links whose children are to be displayed (0 will display the first level of links)
sub_levels	int/null	null	specifies the number of generations of children (of the level specified in `for_level`) to be included (null will display all further generations, 0 will display none)
selected	str	'selected'	specify the class to use for marking selected links
selected_trail	str	'selected_trail'	specify the class to use for marking parents of selected links
selected_for_li	bool	false	indicates if you want the `selected` and `selected_trail` classes to also be applied to the parent element of the link (the `li` tag)
first	str/false	false	specifies the class / turns off classes indicating first links
last	str/false	'last'	specifies the class / turns off classes indicating last links
first_last_for_li	bool	false	indicates if you want the `first` and/or `last` classes to also be applied to the parent element of the link (the `li` tag)

####Displaying a breadcrumb:

• $this->ProMenus->breadcrumb('main', array('separator' => ' → ') displays the breadcrumb for the 'main' menu

#####Options

Option	Values	Default	Description
separator	str	' → '	specifies the separator to be used between crumbs
tag	str	'div'	specifies which tag contains the links and separators
tagAttributes	array	array('class' => 'breadcrumb')	specifies attrubutes for the container tag
