The Navbar has been made a separate module in the theme from version 3.3.0, with its options now in
navbar-options.php. It is still called from the Header (optionally) but it could be placed elsewhere.
The first option for the Navbar chooses between having eight fixed width buttons or allowing the size to vary with the button text.
The second option gives the option to display thin arrows (→ ↓) or thick arrowheads (► ▼) alongside pages that have 'children'.
The next options control the way the menu is built using the
wp_list_pages() function. The first option is used to specify the
depth= argument and specifies the number of levels of the page hierarchy to show. The next six options (replacing the two shown) allow pages, or hierarchies of pages, to be hidden from the menu. There are two that apply all the time, two to exclude extra pages when there isn't a user logged in, and two more that exclude extra pages when there is a user logged in. The values entered are used as the
exclude_tree= arguments so should be comma separated lists of numbers. WordPress doesn't prominently display page numbers but you can typically find them by going to the Pages menu in the dashboard and hovering over the name of the page. Your browser will normally show you the URL the name links to and that includes the number of the page (e.g.
In theory the
exclude= option should exclude individual pages by ID and collapse the hierarchy underneath them, and the
exclude_tree= option should exclude the pages and also all those in the hierarchy underneath them. Prior to WordPress 3.9.0
exclude_tree= had a longstanding bug where it only worked with the first ID listed. However
exclude= still has one where it behaves like
exclude_tree= is meant to if a
depth= argument is used (which it is in the theme). So prior to 3.9.0 excluding more than one hierarchy from the menu only actually worked because of a bug in a WordPress function, and hierarchies still cannot be collapsed because of the same bug (though you probably wouldn't want to anyway).
The outstanding bug has been reported (by me) and has been confirmed and a patch created. Hopefully this will find its way into a release eventually but as of 3.9.1 the bug remains.
The next seven options select the background colour for the three levels of the menu (the default for each is Scout Green changing to Scout Orange when selected) and the background colour for empy slots (Scout Grey (Dark)). The foreground colour is always white. Choosing white is quite reasonable for the empty slots as then there is an empty space between the main menu and the 'Login' / 'Logout' button if it is used.
The next two options control whether the 'Shop' menu entry is shown and allows the URL to be specified. The default is to show a Shop entry and link it to ScoutSHOPS. From version 5.1.1 you can also specify a 'target' attribute for the Shop link (not shown).
The next option controls whether the 'Login' / 'Logout' entry is shown in the menu. The default is to show it. There are then options to select the background colours used for this entry independently of the rest of the menu.
