Hello,
I have a strange problem. On my website I have one category 'resultaten' and I have made a menu item for that.
In another (hidden) menu I have several menuitems linking to one item of the category 'resultaten' for a different view.
But when I click an item from the category view on the page 'resultaten' that also has a menu item in the hidden menu, it is linking the url to the menu-item instead of a subpage of the category view and therefore I am missing my template that is assinged to the itemid of the category 'resultaten'.

For example:
good url: domain.com/resultaten/803-lara-i-1931
bad url: domain.com/lara-2-1926

When I disable seo friendly urls I see in the first url the right itemid 118 and in the second url the itemid 370, the on of the hidden menu item...

Can I change some file that all items from the category view are directed with the right category itemid instead of the hidden menuitemid?

Hello,

Unfortunately this is Joomla!'s behaviour.
Once a menu item exists, then Joomla! will display the item (or whichever piece of content) with the menu item's settings and URL.
