Optimize Toolset

I’ve always been into building performant and accessible sites, but lately I’ve been taking it extremely seriously. So much so that I’ve been building a tool to help me optimize and monitor the sites that I build to make sure that I’m making an attempt to offer the best experience to those who visit them. If you’re into performant, accessible and SEO friendly sites, you might like it too! You can check it out at Optimize Toolset.

About

Hi, 👋, I’m Ryan Hefner  and I built this site for me, and you! The goal of this site was to provide an easy way for me to check the stats on my npm packages, both for prioritizing issues and updates, and to give me a little kick in the pants to keep up on stuff.

As I was building it, I realized that I was actually using the tool to build the tool, and figured I might as well put this out there and hopefully others will find it to be a fast and useful way to search and browse npm packages as I have.

If you’re interested in other things I’m working on, follow me on Twitter or check out the open source projects I’ve been publishing on GitHub.

I am also working on a Twitter bot for this site to tweet the most popular, newest, random packages from npm. Please follow that account now and it will start sending out packages soon–ish.

Open Software & Tools

This site wouldn’t be possible without the immense generosity and tireless efforts from the people who make contributions to the world and share their work via open source initiatives. Thank you 🙏

Dropdown

ES6 class to handle dropdowns with accessibility (a11y) in mind.

Getting Started

Installation

You can install dropdown as part of base.extensions.

npm install @baianat/base.extensions

# or using yarn
yarn add @baianat/base.extensions

If you want the standalone version.

npm install @baianat/dropdown

yarn add @baianat/dropdown

Include necessary files

<head>
  <link rel="stylesheet" href="dist/css/dropdown.css">
</head>
<body>
    ...
    <script type="text/javascript" src="dist/js/dropdown.js"></script>
</body>

HTML Layout

  • .dropdown
    • [data-base-dropdown]
    • .dropdown-menu
<!-- add is-left, is-right or is-center -->
<!-- to style the dropdown position -->
<div class="dropdown">
  <!-- drop down button -->
  <a class="button" data-base-dropdown="#dropdown1">
    <svg class="icon">
      <path d="M12 21.35l-1.45-1.32C5.4 15.36 2 12.28 2 8.5 2 5.42 4.42 3 7.5 3c1.74 0 3.41.81 4.5 2.09C13.09 3.81 14.76 3 16.5 3 19.58 3 22 5.42 22 8.5c0 3.78-3.4 6.86-8.55 11.54L12 21.35z"/>
    </svg>
  </a>

  <!-- dropdown menu -->
  <div class="dropdown-menu"  id="dropdown1">
    <p>Awesome text!</p>
  </div>
</div>

Once you include the script file, it will search for an element with [data-base-dropdown] attribute and initialize new Dropdown instance. Note: you add [data-base-dropdown] attribute to the button element and its value will serve as a CSS selector for the .dropdown-menu

Initialize with JavaScript

If there's no element with [data-base-dropdown] attribute, you have to create a new Dropdown instance manually.

const newDropdown = new Dropdown('#buttonSelector', '#menuSelector', options);

| OPTION | DEFAULT | DESCRIPTION | | ------ | ------- | ----------- | | menuVisible | 'is-visible' | class name for when the menu is visible | | menuHidden | 'is-hidden' | class name for when the menu is hidden | | elementActive | 'is-active' | class name for when the button is active | | hideWhenClickOut | false | set true to close the menu when clicking outside of it |
