- /*
- * post-menu.js - adds dropdown menu to posts
- *
- * Creates a global Menu object with four public methods:
- *
- * Menu.onclick(fnc)
- * registers a function to be executed after button click, before the menu is displayed
- * Menu.add_item(id, text[, title])
- * adds an item to the top level of menu
- * Menu.add_submenu(id, text)
- * creates and returns a List object through which to manipulate the content of the submenu
- * Menu.get_submenu(id)
- * returns the submenu with the specified id from the top level menu
- *
- * The List object contains all the methods from Menu except onclick()
- *
- * Example usage:
- * Menu.add_item('filter-menu-hide', 'Hide post');
- * Menu.add_item('filter-menu-unhide', 'Unhide post');
- *
- * submenu = Menu.add_submenu('filter-menu-add', 'Add filter');
- * submenu.add_item('filter-add-post-plus', 'Post +', 'Hide post and all replies');
- * submenu.add_item('filter-add-id', 'ID');
- *
- * Usage:
- * $config['additional_javascript'][] = 'js/jquery.min.js';
- * $config['additional_javascript'][] = 'js/post-menu.js';
