Understand what you want to do…just not sure how you have your templates set up and what the links should be.
It appears the three links on the right are categories, not specific entries and the link… /index.php/ideas/tag/126#tab-118 ...is to the tag template within the ideas template group. Have no idea what EE tags you’re using in that template and have no idea what the #tab-118 represents.
When I’m on that interim page there is a link to a single entry and that link is… /index.php/ideas/id/urlTitle/#tab-118
It appears then that the links in the right column (categories) link to the “tag” template (a category template) whereas the individual entries appear to use the “id” template…unless of course you are doing something else with your URLs - possible since I don’t have a clue what all the #tab-118 is all about.
If you want those links to get a single entry, wouldn’t you just change the link tags so they point to the “id” template?
I think I’m confused, what am I missing or not understanding about your templating and URLs?
