How to use Page Ids retrieved from Database in the HMenu? - typo3

Question

I'm currently working on my first typo project and need to create a mega menu with an individual set of pages.
Many attempts failed or are not suitable for me. My current shot aims to group pages of the redirect type in a hidden page. In Typoscript I want to set the ID of the parent page containing these redirections and read the shortcut IDs of the children accordingly.
pageIds = CONTENT
pageIds {
table = pages
select {
selectFields = shortcut
pidInList = 614 # Id of the container Page
}
}
The next step would be to use the retrieved shortcut IDs in my HMENU of the type 'list'.
1 = HMENU
1 {
special = list
special {
value = # Assign retrieved IDs here
}
[...]
}
Typoscript is very confusing at first sight, so I would be glad to receive some hints how I can transfer the query's result, as a comma-seperated list, to the HMENU.
Thanks in advance!

First, you need to get a comma-separated list of the page UIDs you want to link. This can be achieved with a renderObj:
lib.pageIds = CONTENT
lib.pageIds {
table = pages
select {
selectFields = shortcut
pidInList = 614 # Id of the container Page
}
renderObj = TEXT
renderObj.stdWrap.field = shortcut
renderObj.stdWrap.wrap = |,
}
This should give you a comma-separated list of all records. Now you must apply these to the HMENU. As you can read in the documentation, the value property is stdWrap enabled, this means that you can copy a value when you use a cObject:
1 = HMENU
1 {
special = list
special {
value.cObject < lib.pageIds
}
[...]
}
I didn't test this, so maybe the configuration is not entirely complete.
