- Invoke the Menu Toggle Adder function similar to the below example. This means that you should add the below code (surrounded by “script” tags) to the html document(s) where your menu is displayed. ‘#menu’ should be replaced by the id attribute assigned to the parent unordered list of your menu.
$(document).ready(function(){ $('#menu').menu_toggle_adder(); });
Menu Toggle Adder Settings
There are several settings that can be specified when invoking the menu toggle
adder function. For example (don’t forget to add the opening and closing
script tags):
$(document).ready(function(){ $('#menu').menu_toggle_adder( { animate_toggle: 'yes', /* 'yes' or' no'. Use "slide down" animation to show and hide nested lists. */ highlight_selected_link: 'yes', /* 'yes' or 'no'. Add "menu_selected" class to the link (and it's parent) that matches the current page name. */ toggle: 'images/toggle.gif', /* Path to the toggle image. This is the image that shows when nested ul is hidden. */ toggled: 'images/toggled.gif', /* Path to the toggled image. This is the image that shows when nested ul is visible. */ toggle_selected: 'images/toggle_selected.gif', /* Path to the selected, toggle image. This is the image that shows when nested ul is hidden and the link url matches the current page name. */ toggled_selected: 'images/toggled_selected.gif', /* Path to the selected, toggled image. This is the image that shows when nested ul is visible and the link url matches the current page name. */ } ); });
Why Use It?
It is tedious for your website user to have to look at a long vertical menu
containing, for example, category and sub category links. Collapsing your sub
category links will allow your website user to find what she is looking for
much easier. Giving the user the ability to expand and contract the menu using
toggle images allows them to inspect the full menu without having to reload
the page.

What Does it Do?
- Finds All unordered lists (ul’s) that have nested ul’s and adds a toggle image.
- Finds the menu link that matches the current url’s page name.
- On page load, all nested ul’s are hidden, except for the one that contains the link that matches the current url’s page name.
- If the menu link that matches the current url’s page name is contained in a nested ul, then both the nested link and parent link get a class assigned of “menu_selected”.
- If the menu link that matches the current url’s page name is contained in a parent ul, then the link gets a class assigned of “menu_selected”.
- Nested ul’s appear and disappear when toggled using the JQuery “slideUp” and “slideDown” functions.
