SEO-friendly Multip Select Dropdown Component – Multi-Checkbox

Description:

Multi-Checkbox is a web component that takes a list of options and converts them into a multi-select dropdown.

Users can select single or multiple options from the dropdown by checking the checkboxes.

Built on top of Custom Element and easy to implement.

How to use it:

1. Import the multi-checkbox.js library as a module.

<script type="module" src="./multi-checkbox.js"></script>

2. Add the multi-checkbox component to the page. Available props:

  • separator: Custom character to used between selected options
  • value: Default value on page load
<multi-checkbox separator="," value="">
  ...
</multi-checkbox>

3. Add a list of options to the multi-checkbox component.

<multi-checkbox separator="," value="">
  <ul slot="check-values">
    <li>CSS</li>
    <li>Script</li>
    <li>Com</li>
  </ul>
</multi-checkbox>

4. Customize the multi-checkbox component by overriding the default CSS variables.
