Hi nikk,
if I understood correctly, you want to link the city names (marked in the screenshot) in the switcher items to a category list or category blog. It seems to me that the city names are part of the content field of each widget item. Therefore, you could create a new menu item of type Category Blog or Category List and then edit your widgetkit items one by one to wrap the link to the category menu item around the city name in the content field.
I would like also that there is a pagination that is to say an article limit in the widgetkit is possible?
Unfortunately, Widgetkit does not have a pagination feature. Also see all these other questions about Widgetkit 2 pagination.
According to this support system's policy of "One question per question" create a new, separate question (= thread) on each issue, please.
When you do so, please provide as much details as possible to improve your chances of getting a useful answer, and of course post a link to your site and a page showing your issue.
Do not ask more than one question at a time, do not add further questions to the same question/thread.
This is not meant to put you off but rather to be able to focus on one issue at a time in order to help you and others with a similar problem.
Kind regards
Thomas
