This plugin will find all available section and categories in your Joomla site and create all menu items link to such section/categories. Once created, menus item will be set to publish status. You can delete or unpublish unnecessary menus.
Install it as other extensions. When done, please select Extensions >> Plugin Manager you will see JA Zin plugin with the name JA Section menu plugin in the list. Please make sure it enabled.
………………….etc
This menu will be created base on your Section structure and Category you’ve had. If you have any changes in your section/category structure, please select Update Setting = Yes in JA Zin configuration page to make change to menu.
Note:
JA Zin used to generate the menu tree for selected section or category. So after you’ve running it and have your desired menu, you can turn it off to save your resource and get a faster load for your site. If you lease it on, menu will be re-generated everytime your page loading.
