Front-end in a tab

For my application I need to have the EDOCMAN category layouts in tabs within my document.

e.g.

[Recent Pubs] [Archived Pubs] [Search] [Viewer]

Where Recent Pubs shows a list of categories from category Parent A
Where Archived Pubs shows a list of categories from category Parent B
Where Search has either Mijo or Smart Search
Where Viewer has an embedded PDF viewer which I will control from customisations.

Effectively I need all of these items to be active on one page so that I am able to control my viewer simply.
I am using Regular Labs Tabs plugin to make the tabs and I've tried using their Components Anywhere to get the desired effect. I get the initial display of the categories but clicking into the category results in a new page being loaded with the documents. I need it to load in the same tab.

Any help would be appreciated. I can supply access to my staging site if needed.

Hi Richard,
You can modify the Category layouts to add your requirement at file
root > components > com_edocman > view > category
and depend on Layout of Category, you can modify the layout file of Category layout:
default.php, column.php, table.php in directory: tmpl
Thanks
