Tabs and Pages::: All tabs are displayed at once

Question

Hi, In my application I have around 100+ pages and grouped together based on specific category. I have a one level tab page as default, and I have grouped the tabs based on the category.
I displayed the tabs when contained in a comma separated page numbers. Then I wanted put these pages in a table and display the tabs when a specific page is selected.
Ex:
pages :1,2,3,4,5 :
Group 1
for display: I used pl/sql return boolean with the following function==== return pagetabs(v('APP_PAGE_ID'))
create or replace function pagetabs (vpageid in number) return boolean is
begin
for crec in select a.pagenum from auditor_pages a, auditor_pages b where b.pagenum=vpageid and a.pagegroup=b.pagegroup
loop
if crec.pagenum = vpageid then
return TRUE;
end if;
end loop;
return False;
end pagetabs;
The problem:
I have all the tabs displayed all the time. My idea is to get the tabs related to that page depending on the category. Can some one suggest a better method or tell me what is the mistake in this process

If it works in Safe Mode and in normal mode with all extensions (Firefox/Tools > Add-ons > Extensions) disabled then try to find which extension is causing it by enabling one extension at a time until the problem reappears.
Close and restart Firefox after each change via "Firefox > Exit" (Windows: Firefox/File > Exit; Mac: Firefox > Quit Firefox; Linux: Firefox/File > Quit)
*https://support.mozilla.org/kb/Troubleshooting+extensions+and+themes
In Firefox Safe mode these changes are effective:
*all extensions are disabled (about:addons)
*default theme is used (no persona)
*userChrome.css and userContent.css are ignored (chrome folder in profile folder)
*default toolbar layout is used
*JavaScript JIT compilers are disabled
*hardware acceleration is disabled (Options > Advanced > General)
*plugins are not affected
*preferences are not affected
