Collapser

Very small CSS & JS dropdown/dropside collapser of menu/list items with no dependencies. It allows you to programmatically create a multi-level, collapsable menu from a nested array data.

API Reference

# bindMenu(data, parent) [<>]

The data is a nested array in a recursive form of [item1, item2, ...]. A menu item is either [item.innerHTML, sub_items, {attribute1: value1, ...}], or [item.innerHTML, click_event_handler, {attribute1: value1, ...}].

import {bindMenu} from './menu.js';
const menu = [
    ["File", [
        [`New`, [
            [`New File`, createNewFile, {backgroundColor: "red"}],
            [`Drama<small>Ctrl+N</small>`, [
                ["Image", createNewImage],
            ]]
        ]],
        [`Save`,],
        [`Load`, () => console.log("Load button clicked.")],
        ['hr'], // Horizontal Line divider.
        [`Import`, importFile],
        [`Export`,]
    ]],
    ["Edit", [
        ["Undo",],
        ["Redo",]
    ]]
];
bindMenu(menu, document.querySelector('menu'));
