Hi, I need to make hundreds of categories and also items. Is there an easy way to do that? I normally make each category one by one, then each item one by one and link them then I make the menus links. Making 5 of these usually takes more than 30 min. Is there a shorter way to do that?Thanks

this may help depending on wether or not you have your content in another format.

Thanks for the info but I am afraid it won't help me. I was hoping maybe a way of creating multiple categories or automated item making or something like a choice to create an item with the parameters of the earlier item (or category) almost like a copy or anything to help me not spend hours on making categories and items and then add menu links. I found a way to make the menu links faster as soon as an item is created (with add menu extension) but there is nothing to make things faster in K2 (although there is one mass category creator extension for Joomla itself but it doesn't help the to do anything for categories in k2).

Another link that may be helpfull.
