的Joomla！ 3.2 - 将全局参数添加到“新菜单项”

Question

I am busy trying to customize Joomla's Menu Parameters so that in the administrator area when you create a new menu item, You have an additional option of "1 Column" or "2 Column", And this has to be both accessible by the index file of the template and also Joomla! Update Friendly..

And this is basically just to give the user the freedom of selecting the layout style of a particular page.

What Would be the Best way to go about this?

Any Help Greatly Appreciated.

UPDATE

what i am trying to achieve is similar to when you select a category for a menu item in Joomla!, I want to append it to the url exactly like a category, so you select 1 of 2 columns when creating a menu item and then in the url it should say: &col=1 or &col=2.

Answer 1

Joomla already has a built in parameter for selecting the layout used for a menu item which is the concept of an alternative menu layout. You add the layout to your template html folder with the appropriate xml file. Then that layout will show up in the list of menu options when you select a menu type.
