HMENU only pages with a specific value in custom field - typo3

Question

I have a custom field (lets say its named myfield) in the table pages with the values 0, 1 or 2. I now want to create a HMENU for all pages that have a specific value (for example all pages with myfield=1) in this field.
How could I get this?
As far as I know I can not add a where-clause to the HMENU. So will I need a USER_INT for it?
Will it work somehow like this:
includeLibs.something = mypath/user_myclass.php
lib.servicenav = HMENU
lib.servicenav {
special = list
special.value = USER
special.value.userFunc = user_myclass->myFunction
special.value.myfieldvalue = 1 # 0, 1, or 3
}
user_myclass.php->myFunction:
function myFunction($a, $myfieldvalue) {
// - search all pages with $myfieldvalue
// - add all pids of this page to the returnvalue (as string)
$returnvalue = "5, 19, 200";
return $returnvalue;
}
Will this solution work? Are there better solutions?
Edit: cascavals solution:
It works in a small testproject with this:
lib.menu = HMENU
lib.menu{
special = list
special.value.cObject = CONTENT
special.value.cObject {
table = pages
select {
where = myfield=0
}
renderObj = TEXT
renderObj {
field = uid
wrap = |,
}
}
entrylevel = 1
1 = TMENU
1.NO = 1
1.NO.linkWrap =
<div class="menu">|</div>
überschreibt
2 < .1
2.NO.linkWrap =
<div class="menu-ebene2">|</div>
But it does not work in a bigger project with this (I get no output):
Also when I copy the Menu from above it does not work in this project..
lib.navigation = HMENU
lib.navigation {
special = list
special.value.cObject = CONTENT
special.value.cObject {
table = pages
select {
where = myfield=0
}
renderObj = TEXT
renderObj {
field = uid
wrap = |,
}
}
1 = TMENU
1 {
noBlur = 1
expAll = 0
wrap = <ul class="nav1">|</ul>
NO = 1
NO {
wrapItemAndSub = <li class="first">|</li> |*| <li>|</li> |*| <li class="last">|</li>
altText = subtitle // title
title = subtitle // title
}
CUR < .NO
CUR.ATagParams = class="active"
CUR.wrapItemAndSub = <li class="current first">|</li> |*| <li class="current">|</li> |*| <li class="current last">|</li>
ACT < .CUR
ACT = 1
ACT.ATagParams = class="active"
}
2 = TMENU
2 < .1
2 {
expAll = 0
wrap = <ul class="nav2">|</ul>
}
}

As special.value has stdWrap, you can still select page UIDs dynamically and create a comma-separated list that is expected:
lib.servicenav = HMENU
lib.servicenav {
special = list
special.value.cObject = CONTENT
special.value.cObject {
table = pages
select {
pidInList = [UID of the root page of your website]
recursive = 99
where = myfield=1
}
renderObj = TEXT
renderObj {
field = uid
wrap = |,
}
}
}
