Installation

Option 1 - HTML

Add the following script tag to your index.html:

<script src="http://unpkg.com/slide-panel/dist/slide-panel.min.js"></script>

Option 2 - React, Angular or Vue

Install the package to your project:

npm install slide-panel

Add the following in your entry file e.g. index.js:

import "slide-panel"

Usage

Use the slide-panel tag and add the contents of the panel within <div> tags.

Add position with either the following values: left, right, top or bottom to set where the panel is sliding in from. If position is not included, the panel will slide in from the left by default.

Add transitionDuration with a value in milliseconds to set transition duration of the panel closing and opening. If transitionDuration is not included, the transition duration will be 300 by default.

The open property is used to determine whether the panel is opened or closed.

<slide-panel class="panel" transitionDuration="500" position="right">
  <div><!-- ADD CONTENT HERE --></div>
</slide-panel>

<button id="btn">Open Panel</button>

<script>
  const btn = document.querySelector("#btn");
  const panel = document.querySelector(".panel");

  btn.addEventListener("click", (event) => {
    panel.setAttribute("open", "true");
  });
</script>

Props

Events

slide-panel-open is a Custom Event that is emitted when the panel opens.

slide-panel-close is a Custom Event that is emitted when the panel closes.

An event listener can be added to the panel to listen to these Custom Events. Continuing on from the previous example:

<script>
  panel.addEventListener("slide-panel-open", (event) => {
    console.log("Slide Panel Opening 🚀");
  });
</script>

Styling

slide-panel utilises CSS variables that help style the component. These can be overridden to adjust the styling. The amount of styling is intentionally lean to allow the user to focus on styling the panel.

To override the CSS variables, it is recommended to add a class to the slide-panel tag and define the CSS variables in that class. The values used below are the default values.

.panel {
  --slide-panel-root-z-index: 1200;
  --slide-panel-panel-z-index: 1000;
  --slide-panel-backdrop-background-color: rgba(0, 0, 0, 0.5);
  --slide-panel-background-color: #ffffff;
  --slide-panel-box-shadow: 0px 2px 3px -1px rgba(0, 0, 0, 20%), 0px 4px 6px 1px
      rgba(0, 0, 0, 14%), 0px 3px 8px 1px rgba(0, 0, 0, 12%);
  --slide-panel-transition-timing-function: ease-in-out;
}
