Multi-Level Menu

A simple multi-level menu with delayed item animations and an optional breadcrumb navigation and back button.

From our monthly sponsor: Automate manual QA and catch visual bugs with Percy’s all-in-one visual testing and review platform.

Today’s Blueprint is a simple menu with multiple levels. The idea is to animate each menu item once a level is changed. The animation starts with the item clicked and the delays are propagated through the neighbors. The animation delays follow the same logic for the incoming items of the new level of the multi-level menu. As optional elements we have a breadcrumb navigation and a back button (not shown in our demo). Deeper levels are referenced with a data attribute. We have added some example media queries for a mobile menu version with a menu toggle. We’ve also provided a simple callback example.

The icons used in the demo are from the Organic Food icon set by Wojciech Zasina and the Feather icon set by Cole Bemis.

Please note that we are using a couple of modern CSS properties, so only modern browsers are supported.

How can I get the links to go to html files? I want to integrate with WordPress but when I try to use external links as suggested by @Raymond above, the menu disappears. Anyone had any success with this?
- Ardian June 22, 2017 at 13:45
  
  In order to work the external link (the last one with href),just delete the “onItemClick” so: onItemClick: loadDummyData – also the loadDummyData(){…} function.
  
  P.S – on the demo link “https://tympanus.net/Blueprints/MultiLevelMenu/” the menu works on my iphone 4s, but when I download the source, I click on the menu and it doesn’t open. This is very strange, is there any different script called online (which I dont think so). Any idea ???

Hey, thanks very much. for this awesome blueprint. I have an urgent request. I tried to use this blueprint as a non-ajax Main-Navigation for a CMS. After figuring out the current page and the related submenu I set the according index to this.current in the JS-File. The according submenu is opening when a subpage is loaded, which is fine, but the breadcrumbs and back controls are not behaving accordingly, because it thinks the opened submenu is the new root-level. I already opened an issue on GitHub, but no answer so far. Any ideas on how to set/open a submenu on initialization?

This plugin is awesome, but I have problem with crossbrowser test. It says multybrowser support, how I can run on IE10+ and Microsoft Edge. Menu is blank even if I already allow block content.

  Did you find any solution to this problem? I am experiencing the same problem
James August 4, 2017 at 13:05

Do you really need all that JavaScript ??

What if I just wanted a menu with different levels could I just use JQuery(Hide/Show/AddClass) etc etc I’m not bothered about the history displaying links either ?

This is awesome! just wondering if anyone knows if there’s a React version of this sort of thing? Otherwise I might have crack at making one.Thanks for building this, Captain Tympanus 🙂

Did anyone solve the problem of this plugin not working on Internet Explorer?
Indah Ramayani January 11, 2018 at 13:15

this not work on internet explorer. but this very awesome menu.
wong January 26, 2018 at 13:15

The online version is working well at IE, but the download version not working…. 🙁
Lauren Barker February 15, 2018 at 19:49

Major props for such a good UX and creative way to make deep navigation beautiful. Using it a current project and will submit a pull request once I’ve added some features mobile vs desktop versions.

FYI for those wondering about browser compatibility issues – Looks like the main.js file is different from the version supplied within the repo. When I updated my local version to use the exact main.js code from tympanus.net instead of the downloaded version or repo, compatibility issues for IE 11 and safari were solved.

Any idea how to disable the animations and still have the menu work? I have created a dynamic menu which can take database items and generate a menu, however modernizer or classie keeps disabling the menu when I disable animations. It’s about efficiency with the dynamic menu and the animations are really slowing it down. Even if I set the delays to like .01 JS will stop the menu from working.

Any help on completely removing classie.js and modernizer would be awesome. Thank you.

I would like to show the backCtrl Back Button. How do I do this?
Zoran Wolf May 17, 2018 at 17:41

Is it possible to add a Back Button and have the breadcrumbs? Where is the backCtrl set to false?
