Override HMENU that is included in another template

Question

In TYPO3 4.7 I have a template that contains:

page.10 < temp.mainTemplate

This Template has two includes. The first contains this:

temp.mainTemplate = TEMPLATE
temp.mainTemplate {
  subparts.menu_1 < temp.menu_1
}

And the second contains the actual HMENU typoscript:

temp.menu_1 = HMENU
temp.menu_1 {
  #My Menu
}

Without altering either of the includes, how can I make an edit to the HMENU in the main template setup?

I have tried this above the first line without success:

temp.mainTemplate.subparts.menu_1 {
 #Modifications to My Menu
}

I have tried this below the first line without success:

page.10.subparts.menu_1 {
  #Modifications to My Menu
} 

Answer 1

page.10.subparts.menu_1 is the right key to alter. It needs to be places after page.10 < temp.mainTemplate of course.

you can test it by deleting the menu completely with page.10.subparts.menu_1 > and it should disappear from the webpage.

There is no way of telling what exactly does not work without seeing more of your TS. May be you have just a typo somewhere
