Delegated Dropdown

Mobile-first delegated dropdown menus with smart positioning.

  • Handles tap events
  • Opens the dropdowns either up or down
  • Justifies the content either to the left or the right of the parent
  • esc closes all dropdowns
  • Only one dropdown menu open at a time

Caveats:

  • You may need to set overflow: hidden
  • You need to handle :hover states yourself

API

.Dropdown(.open)(.up)(.down)(.left)(.right)
  .Dropdown-toggle
  .Dropdown-menu
    .Dropdown-item

View index.css for the HTML structure.

var dropdown = require('delegated-dropdown')

Note that these methods are completely optional.

dropdown.on(event)

Dropdown is an emitter. The events are:

  • open <dropdown> - when a dropdown is opened
  • close <dropdown> - when a dropdown is closed

dropdown.position(el)

Positions a .Dropdown element.

If you do not position your dropdowns, you probably want to set overflow: hidden to prevent any accidental scroll bars.

dropdown.open(el)

dropdown.close(el)

dropdown.clear()

Clears all dropdown menus.
