droplab

DropLab

A generic dropdown for all of your custom dropdown needs.

Install

• Add /dist/droplab.js to your application assets.
• Link to them in your code. See examples.

Usage

Adding the data-dropdown attribute to your dropdown will add a droplab hook for that element.

The id of the hooked element can be used as the value of the data-dropdown-trigger attribute of a different element to use it as a toggle.

<a href="#" data-dropdown-trigger="#some-dropdown">Toggle</a>

<ul id="some-dropdown" data-dropdown>
  <!-- ... -->
<ul>

You can also have an input as the trigger. When a user types, the dropdown will appear.

Static data

You can add static list items.

<a href="#" data-dropdown-trigger="#static-dropdown">Toggle</a>

<ul id="static-dropdown" data-dropdown>
  <li><a href="#">Jacob</a></li>
  <li><a href="#">Jeff</a></li>
  <!--  ... -->
</ul>

Dynamic data

Adding data-dynamic to your dropdown element will enable dynamic list rendering.

Data can be added using the DropLab.prototype.addData function. The first argument is the data-id of your trigger element and the second argument is an array of objects to render to list items.

You can template a list item using the keys of the data object provided.

<a href="#" data-dropdown-trigger="#dynamic-dropdown" data-id="dynamic-trigger">Toggle</a>

<ul id="dynamic-dropdown" data-dropdown data-dynamic>
  <li><a href="#" data-id="{{id}}">{{text}}</a></li>
</ul>

droplab.addData('dynamic-trigger', [{
    id: 0,
    text: 'Jacob'
  }, {
    id: 1,
    text: 'Jeff'
  }]);

Examples

Some example implementations are provided in /example.

Plugins

Plugins are functions that are registered to be executed when a droplab instance is initialised.

They are passed the DropLab function.

droplab.plugin(function somePluginFunction(DropLab) {
  // ...
});

Some plugins are available in /dist/plugins.

Then you can run tests with npm test.

Scripts can be compiled into /dist with npm run compile.
