#Trees

A tree is a CSS only list that lays out menu-items in a vertical menu with a toggle.

#Structure

A tree has children that are denoted with the tree-item class. The tree-item can then have menu list of menu-items in the tree-item-body with the title above it being a tree-item-header.

Structure
  • tree
    • input - this input must either be a checkbox or radio. The input must also use the u-none class. The id must be the same as the associated tree-item-header.
    • tree-item-header - the label that the user will click on to toggel the dropdown.
    • tree-item-body consists of the menu to be shown.

#Basics

The toggle is created by a simple input (checkbox or radiobutton depending on the behavior you want) with a check property.

#Tree Nav Layout

A great way to use the tree class is by embedding it inside a tree-nav as a fixed menu on the side of the page.

Structure
  • tree-nav-body
    • tree-nav-header - holds a link used to trigger the sidebar to appear. Visible on tablet or smaller screen dimensions.
    • tree-nav - sidebar that appears on the left.
      • tree - the tree component mentioned above containing different menu options.
    • tree-nav-close - link used to represent a close button for the menu. Visible on tablet or smaller screen dimensions.

For mobile devices (<= 768px), the tree-nav-header will be visble to show a toggle switch to show the tree-nav.
