menu - Typo3 list the content of all child-pages as content of the parent page -

as title says, need list content of child-pages on parent-page, after own content. or thing need is, 1 page content , and menu links different headers of content. e.g. athe parent-page content:

**parent head** parent text *first subhead* first subtext *second subhead* second subtext 

and menu should like:

parent

-first subhead

-second subhead

i thought easier if parent-page "collects" content of child-pages. other solution was, child-pages links extern urls, specific c-ids of different contents of parent-page. think isn't easy website owner, doesn't know can find right c-id in web-page-source-code. how make that? or how can realize thing child-page-content?

edit: have solution now. have fix, submenu displayed without childpages. here code:

temp.contentnav = content temp.contentnav {   table = tt_content   select {     pidinlist = 7     orderby = sorting     = 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="linkclass"     if.istrue.field=header   }    wrap = <ul id="submenuclass"> | </ul> }  page.10.marks.menu.2.no.after.cobject < temp.contentnav 

try this

temp.pageids = hmenu  temp.pageids.entrylevel = 1  temp.pageids.1 = tmenu  temp.pageids.1 {    no.stdwrap.field = uid    no.allwrap = |,    no.donotlinkit = 1  }  lib.container = content  lib.container.table = tt_content  lib.container.select {    pidinlist.cobject < temp.pageids  }
