Could you please clarify what exactly you want to edit?
Do you wish to change the links for languages?
If you want to use some widget in top header area you can insert it into “Place in header top bar” widget area in Appearance > Widgets.
I’ve made a screenshot of the demo site in order to show what area I’d like to be able to edit (or add widgets in) and circled/rectangled the area in red for you to highlight it. The reason I used the demo site as an example is because the site I am working on is not being used as a commerce shop, so the wishlist/signin/register/cart and search links are useless. When I enable the “toplinks” area in the Theme’s settings page, I only see a ‘logout’ link and there is no clear way where I can add a widget (in this case, just a link using a text widget) into that area.
If you don’t need those links you can disable them in admin panel > Theme Options > Header.
After that use the widget area described in the previous post to insert your widgets.
If you want to create your own links you need use Text widget and insert your code into there.
That’s still unclear. In my original post I asked the question which still isn’t answered: WHICH widget area covers that part of the page? And which of the “switches” on the “Header” section of the Theme Options should be on or off?
I have tried switching various options on or off, and I’ve also tried placing the widget into different areas – none of these have put the widget in the area I would like, and none of the labels clearly indicate that area will be affected.
To change top links “Register”, “Sign In”, “Wishlist” you need edit the files header.php (line 186) in wp-content/themes/legenda directory and theme-functions.php (from line 982) in the directory wp-content/themes/legenda/framework. Cart widget can be disabled in Theme Options > Header if you don’t need it.
