typo3 show submenu without subpages - typo3

Question

I have a website with some pages, presented in a normal menu. Every page has subpages and shows them in a submenu. Except one page. This page has no subpages and should have a content menu which navigates to different content sections on the page. The thing with the content navigation is done with:
temp.contentnav = CONTENT
temp.contentnav {
table = tt_content
select {
pidInList = 7
orderBy = sorting
where = colPos=0
languageField=sys_language_uid
}
renderObj = TEXT
renderObj {
field = header
wrap= <li>|</li>
typolink.parameter.field=pid
typolink.parameter.dataWrap=|#{field:uid}
typolink.ATagParams = class="linkSubpage"
if.isTrue.field=header
}
wrap = <ul id="subMenu"> | </ul>
}
page.10.marks.MENU.2a.NO.after.cObject < temp.contentnav
but this works only if the page has at least one subpage. The workaround would be to add a subpage and hide the submenulink, but is there a better solution to show the custom submenu without adding subpages?

Answer 1

Use a HMENU item with the levels to generate your submenu.
Your behavior is not the right one in the TYPO3 working style. Use the rights TypoScript objects.
And remove the "a" from the "page.10.marks.MENU.2a.NO". The correct use is 1,2,3,...
