Multi-Level Accordion Menu

A simple CSS accordion menu with support for sub level items.

Today’s resource is a handy accordion menu with support for groups/subitems. It works with CSS only, using the :checked pseudo-class selector on the checkboxes input elements. However we included a version with jQuery as well, in case you prefer a subtle animation compared to the instant default effect. Your call!

The first user case I can think of for this resources is a “layer organizer”. Think of Sublime Text sidebar, or Photoshop layer window. Anyway, I’m sure you’ll find a use for this new snippet to store in your arsenal ;)


Creating the structure

The HTML structure is pretty simple: the accordion is an unordered list. If a list item contains subitems, then we insert an input[type=checkbox] and its label. Also, we add the .has-children class to the list item. All “standard” list items contain just an anchor tag.

Adding style

We use a smart (and quite standard nowadays) technique to detect the click and show sub content with CSS only: by including a checkbox input element, we can use the :checked pseudo-class and the adjacent sibling selector (div + div) to change the display mode of the sub <ul> element from “none” to “block”.

Step by step: first of all, we have to make sure that the checkbox input element covers the entire list item that contains subitems. Put in other words: we need to create a custom checkbox. So, firstly, you need to make sure that when you click on the label, the checkbox is checked/unchecked as well. This is achieved by using the “for” attribute inside the label (label “for” attribute = input “name” and “id” attributes. See html section above). This way you can simply hide the input element and work with the label instead.

Now notice in the HTML structure that input, label and the unordered list (that we make visible on click) are siblings. By using the :checked pseudo-class, you can set the following process in motion: when the checkbox input is checked (click on label), then take the <ul> sibling element and change its display value from “none” to “block”:

If you want to gently animate the opening phase, then include the .js file as well. Also remember to add the .animate class to the main .cd-accordion-menu element (this will animate the arrow rotation).

    it is a nice , but it’s working only like vector design .not like flate design

    • brendan

      lol wut

  • Luke Edwards

    You can still have the CSS version animate as the jQuery version does. Like the color palette

    • Sebastiano Guerriero

      hey Luke! True, but you should set a fixed height for the hidden elements, which is ok in some cases, not so convenient in others

      • Chris

        Or you could animate max-height instead: I don’t really like this solution, but it seems to be the best one.

        • idol chan

          this solution introduces uneven delayed animation. bad UX indeed.

  • Yimiprod

    you can use the tilde selector (~) instead of +

    • Andy Man

      Why? You want to select the adjacent selector of the first element that is immediately preceded by the former selector. ~ is less strict, so more prone to errors.

  • Courtney Artuso

    Very nice. I noticed when opening a parent the child icon jumps to the right it seems that the closed folder icon has a smaller width than that of the open folder icon thats causing the jump. Other than that its very nice.

  • Chu Quang Tú

    Briliant ! Thanks mate

    Has anyone an idea how to define attributes of parents which are open (different background-color etc.)?

    • Philipp

      this worked for me:

      .cd-accordion-menu input[type=checkbox]:checked + label {
      color: #fff;

  • Fernando Silva

    Very nice, many thanks. Just one question, the transition when the display changes from none to block is not working for me =/

  • Kenneth Kerr

    Thanks for this solutions it works pretty well. I have a question: How do I keep all of the accordions collapsed when a user enters the page for the first time?
    Thanks for the help.

    • Kenneth Kerr

      Got it… There is a checked attribute that needs to be removed from the input tag…


    Great and neat solution
    For now the jquery version works in IE8 without a problem

    However, what if i change the input type to a radio button where selecting one panel closes the other panels with the same name attribute, Now i have made the appropriate CSS changes from checkbox to radio and it works as desired. What changes do i have to make to the jQuery code so that it behaves as the CSS version where opening a closed panel closes the currently opened panel

  • Techno

    Nice looking menu. Great job
    I’m wondering how to move a child icon to the left. in other words, is there a way to align the parent and the child icon exactly at the same position. if not, how to reduce the left margin of the child icon?
