Sometimes for mobile design or more generally small-screen design it can be beneficial to save space by using a dropdown for your navigation.
This plugin provides a way to display your custom menus as dropdowns either using a widget or a function call and can be used as an include in any theme.
Usage
If you are using the plugin with a theme you can use the function dropdown_menu() in place of calls to wp_nav_menu().
The dropdown_menu() function takes the same arguments as wp_nav_menu() with the addition of three extras:
'-- Main Menu --',
// indent_string is a string that gets output before the title of a
// sub-menu item. It is repeated twice for sub-sub-menu items and so on
'indent_string' => '- ',
// indent_after is an optional string to output after the indent_string
// if the item is a sub-menu item
'indent_after' => ''
) );
?>
You can extend and alter the output of the dropdowns using the output filters available in the code.
There are also plenty of styling hooks like in the standard list type menus with the addition of classes for targetting items at a certain depth in the menu (.menu-item-depth-1 for example) aswell the usual .current-menu-item and .current-menu-ancestor classes.
Filters/Hooks
dropdown_blank_item_text
If you want to show the menu title as the blank item text use the follwing code:
menu->name . ' -';
}
?>
dropdown_menus_indent_string
dropdown_menus_indent_after
dropdown_menus_class
Use this if you find you get class name or CSS conflicts, for example with Twitter Bootstrap.
dropdown_menus_select_current
Use this filter to stop the output of the selected="selected" attribute. Useful if you prefer to show the blank option on every page.
