Basic dropdown

The dropdown is working with a .dropdown class on an element. To trigger it, you have to add a .data-target refering to the dropdown element inside of it.
The dropdown is working with our color palette.

Right aligned dropdown content

To align your dropdown content with the right border of the dropdown trigger, you just have to add the .dropdown-right class on your .dropdown-content.

Constrain width

To constrain the width of the dropdown content to fit the dropdown trigger width, just add the .dropdown-constrain-width class to your .dropdown-content element.

A dropdown is easily usable inside a navbar, using a .navbar-link as a dropdown trigger.

Animated dropdown

The animationType option is activable through the JS initialization. the 'fade' one is creating a smooth fade in animation of the dropdown content.
Note that this option is not working with the hover option.

JavaScript initialization

Once HTML was setup, you can activate the dropdown with this simple code.
Just pass the id of your dropdown that you want to activate.

To know all the ways to initialize a JS component, please read the JS Init page.
