show list of records chosen by a category in a category tree on a separate page

Question

TYPO3 11.5.12, events2 8.0.1

I get the used categories of a calendar (https://www.my-domain.de/lehre/kalender) in a category tree with the following fluid

<ul>
    <f:for each="{selectorData.categories.main}" as="category" iteration="catIterator">
        <li>
            <a href="{f:uri.page(pageUid: '{data.pid}', additionalParams: '{tx_events2_searchresults: {search: {mainCategory: \'{category.uid}\'}, controller: \'Search\', action: \'listSearchResults\'}}')}">{category.title}</a>
        </li>
    </f:for>
</ul>

After clicking on a category I want to show all records that are related to this category on a separate page (https://www.my-domain.de/lehre/kalender/filter). Right now, the URL changes to https://www.my-domain.de/lehre/kalender/name-of-the-category and the list of the events is the same. What plugin has to be inserted on the page filter and what do I have to do that the chosen category for the selection of the records is used on the page filter?

Answer 1

It's difficult in TYPO3 (or in general) to combine data from several tables in the URL.
Therefore the most simple and reliable approach is to create for each category a distinct page, there you can likely limit the output from events2 to the one category only (Sorry, I never used events2,so I never know for 100%).
