Category menu for tx_news that adds a category to the existing list view instead of replacing it

Question

I have a list view, showing news of a specific category A.

I want to further limit the list by one additional category the user can select.

I add a category menu to the page. The list view page is the same as the initial list view page.

After the user chooses a category B from the category menu, the page displays the news items with category B.

Instead of this, I want the news items that are of the initial category A and the user selected category B.

How would I do that?

I ended up overriding the category template and hardcoding there the generated links. The line additionalParams="{tx_news_pi1:{overwriteDemand:{categories: category.item.uid}}} became additionalParams="{tx_news_pi1:{overwriteDemand:{categories: '{category.item.uid},XXXXX'}}} where XXXXX is my additional category — Stefanos Karasavvidis

You need to build a link holding both category IDs. Currently it is not implemented that you can provide an additional category.
