Usage

To use Tendina, you just need to have some basic markup for your menu.

That means you'll have some nested unordered lists, like this:

<ul id="menu">
  <li>
    <a href="#">Menu 1</a>
    <ul>
      <li><a href="#">Submenu 1</a></li>
    </ul>
  </li>
  <li>
    <a href="#">Menu 2</a>
    <ul>
      <li><a href="#">Submenu 2</a></li>
      <li><a href="#">Submenu 2</a></li>
      <li><a href="#">Submenu 2</a>
        <ul>
          <li><a href="#">Subsubmenu 2</a></li>
          <li><a href="#">Subsubmenu 2</a></li>
        </ul>
      </li>
    </ul>
  </li>
  <li>
    <a href="#">Menu 3</a>
    <ul>
      <li><a href="#">Submenu 3</a></li>
      <li><a href="#">Submenu 3</a></li>
    </ul>
  </li>
</ul>

Any menu that doesn't have child menus will be treated like a normal link.

Heads up! Tendina uses <a> tags for DOM traversing and click events management. Don't let them out! 🐺

Next step is to have jQuery (>= 1.7.x) and Tendina loaded in your page:

<script src="http://code.jquery.com/jquery-1.11.0.min.js"></script>
<script src="tendina.js"></script>

Finally, you can simply call the function on your list to transform it in a snappy side menu:

$('#menu').tendina()

What Tendina does

• Provides a super easy way to setup sidemenus in a matter of minutes
• Supports infinite levels of nesting
• Hides your nested submenus and manages all interactions
• Handles dinamically added elements (nice to have when building a menu from a JSON)
• Supports multiple menu initializations on the same page
• It's lightweight – 3kb minified!

What Tendina does not

• Improve your social life
• Pollute your stylesheets with unnecessary CSS (read below)

I made this plugin just to handle menu interactions in a flexible way. As a result, Tendina comes with no styles at all. This means you don't need to override useless CSS classes, and you have total control on the styling of your menu. Additionally, Tendina will add a "selected" class to the currently opened menu, so you can customize its looks without adding other Javascript code.

Options

Tendina accepts an option object, just like that:

$('#menu').tendina({
  animate: true,
  speed: 1000,
  onHover: true,
  hoverDelay: 300,
  activeMenu: $('.my-active-menu'),
  openCallback: function(clickedEl) {
    clickedEl.addClass('opened');
  },
  closeCallback: function(clickedEl) {
    clickedEl.addClass('closed');
  }
});

Animate

boolean (default: true)

animate: true

Set to false if you don't want to have slideUp/slideDown animations.

Speed

integer (default: 500)

speed: 1000

Animation speed in milliseconds. Works only if animate is true.

onHover

boolean (default: false)

onHover: true

Set to true if you want Tendina to open menus on mouse hover.

hoverDelay

integer (default: 200)

hoverDelay: 350

The delay after which Tendina will open menus on hover. The default value fits almost any use case, but if you want to finetune it, go for it!

activeMenu

string or jQuery object (default: null)

activeMenu: '.my-active-category'
// or
activeMenu: $('.my-active-category')

The active menu that will be open when a new Tendina menu is created. This is very handy if you want to show your users where they are, since Tendina will add the "selected" class to the active menu (and its parents). You can pass a selector option or a jQuery object.

openCallback

function (parameters: clickedEl)

openCallback: function(clickedEl) {
  console.log(clickedEl); // Returns clicked jQuery <li> object
}

Callback that will be executed once any menu/submenu has been opened.

closeCallback

function (parameters: clickedEl)

closeCallback: function(clickedEl) {
  console.log(clickedEl); // Returns clicked jQuery <li> object
}

Callback that will be executed once any menu/submenu has been closed.

I'm working on adding more options in the next versions. Feel free to open an issue if you think Tendina should include any particular option!

Methods

Tendina comes with a few handy methods.

destroy

$('#menu').tendina('destroy')

Will unbind all events, remove all helper classes and open all menus, restoring the unordered list state before Tendina was called.

hideAll

$('#menu').tendina('hideAll')

Will hide all open submenus.

showAll

$('#menu').tendina('showAll')

Will show all submenus.

I'm working on adding more methods in the next versions. Feel free to open an issue if you think Tendina should include any particular method!

Contributing

Contributions are welcome! In order to contribute, you can use the Fork & Pull Model.

Tendina comes with a easy-to-use Grunt configuration.

Given you have npm and grunt-cli installed, you just need to run npm install in the project folder once to install all the dev dependencies. Then, just execute grunt watch: this way Grunt will spawn a watcher that will compile the Coffee and minify the resulting Javascript everytime you edit tendina.coffee.
