Dropdown

Introduction

Add a dropdown list to any button. Make sure that the data-activates attribute matches the id in the <ul> tag.

You can add a divider with the <li class="divider"></li> tag.


  <!-- Dropdown Trigger -->
  <a class='dropdown-button btn' href='#' data-activates='dropdown1'>Drop Me!</a>

  <!-- Dropdown Structure -->
  <ul id='dropdown1' class='dropdown-content'>
    <li><a href="#!">one</a></li>
    <li><a href="#!">two</a></li>
    <li class="divider"></li>
    <li><a href="#!">three</a></li>
    <li><a href="#!"><i class="material-icons">view_module</i>four</a></li>
    <li><a href="#!"><i class="material-icons">cloud</i>five</a></li>
  </ul>

Options

Option Name	Description
induration	The duration of the transition enter in milliseconds. Default: 300
outduration	The duration of the transition out in milliseconds. Default: 225
constrainwidth	If true, constrainWidth to the size of the dropdown activator. Default: true
hover	If true, the dropdown will open on hover. Default: false
gutter	This defines the spacing from the aligned edge. Default: 0
beloworigin	If true, the dropdown will show below the activator. Default: false
alignment	Defines the edge the menu is aligned to. Default: 'left'
stopPropagation	If true, stops the event propagating from the dropdown origin click handler. Default: false

To use these inline you have to add them as data attributes. If you want more dynamic control, you can define them using the jQuery plugin below.


  <a class='dropdown-button btn' data-beloworigin="true" href='#' data-activates='dropdown1'>Drop Me!</a>

jQuery Plugin Initialization

Initialization for dropdowns is only necessary if you create them dynamically.


  $('.dropdown-button').dropdown({
      inDuration: 300,
      outDuration: 225,
      constrainWidth: false, // Does not change width of dropdown to that of the activator
      hover: true, // Activate on hover
      gutter: 0, // Spacing from edge
      belowOrigin: false, // Displays dropdown below the button
      alignment: 'left', // Displays dropdown with edge aligned to the left of button
      stopPropagation: false // Stops event propagation
    }
  );

You can also open dropdowns programatically, the below code will make your modal open on document ready:


  $('.dropdown-button').dropdown('open');

You can also close dropdowns programatically:


  $('.dropdown-button').dropdown('close');
