Dropdown Menus

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:

<?php
dropdown_menu( array(

    // You can alter the blanking text eg. "- Menu Name -" using the following
    'dropdown_title' => '-- 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.
