Original Pre-Enfold Menu Will Not Display, only Enfold boilerplate menus

When I first downloaded Enfold, it would show in the parent theme. But I can’t get it to work on the child theme and I did import my options from parent theme.

When I see it and want to select it for use, it says the following:
“Enfold Child Secondary Menu – will be displayed if you selected a header layout that supports a submenu” (it would be helpful if instead of this blanket statement, it stated the header layout options necessary, instead of making the user guess).

However, when I go to the Header Layout Tab, in Enfold Child Theme Options – I have tried every layout change I can think of, and none of them allow my original menu to show.

Will you please tell me which Header Layout Options need to be selected to enable the use my original menu, with submenu as dropdowns?

***EDIT*** It wasn’t under Header Layout Options:
Fixed… Thanks, I wanted my main menu to be my pre-existing, pre-Enfold menu, but when I selected my old menu it would not show. I did get it to show, but I had to select the Enfold Main menu first, which defaults to the Enfold boilerplate menu (which I did not want). Once the boilerplate menu was showing, *and SAVED* (seems counter-intuitive, no?), I had to go back to “Menu’s”, still under the Customization section.

Then, I had to select “Previously used Menu 1” (which in my previously used WP themes would have been my first and only step under Customizations), scroll to the bottom and select “Enfold Child Main Menu”, under Display Location.

I wonder, if I had made my own Child Theme, as opposed to downloading the Enfold child theme, if this would have been the same set-up?

The question NOW is, what is included in that Enfold Child Theme download, that would change the way the parent theme acted? I ask because I am wondering, what the advantage of the Enfold created Child Theme is. Is it just a convenience for your customers (which is nice, thank you), or is there customization that will effect future use (outside of a normally created Child Theme)? Since I am not a developer, I am thinking, it might be better to create my own child theme, if there is advanced customization within the Enfold created Child Theme, that behaves differently than normal WordPress child themes (created by me or other WP codex readers), which a non-developer would not easily recognize, and thus struggle with.

Two more follow-up questions:
1. Enfold Child Theme – does it update when the parent theme has an update, but still keep my customization (as a regular child theme would)?

2. If the Enfold Child Theme does include customization outside of what a brand new (pre-customized) customer created child theme would include, what are they, what would they effect?

Thank you again. :)
