[Victor Livakovsky]

>> I have such menu:
>>
>> temp.submenu = COA
>> temp.submenu.wrap = <div class="sub">|</div>
>> temp.submenu.10 = TEXT
>> temp.submenu.10.value = <div class="subheader">{$Name} -

>> temp.submenu.20 = HMENU
>> temp.submenu.20.wrap = <div class="submenu">|</div>
>> temp.submenu.20.entryLevel = 1
>> temp.submenu.20.1 = TMENU
>> temp.submenu.20.1 {
>>   NO.wrapItemAndSub = <p>|</p>
>> }
>>
>> And I want it be visible only on that pages, which has subpages. I was

> temp.submenu = COA
> temp.submenu {
>   wrap = <div class="sub">|</div>
>   10 = blah
>   ...
>   20 = blah
>   ...

Thnk you very much! :) Your advise was helpful!
Finally it works, as it should work.
I only added
pidInList.data = field:uid
to "select" in your code.
