High Performance Select Box JavaScript Library – Virtual Select

Preview:

Description:

A high-performance, Material Design style select box replacement that supports single/multiple select, virtual scrolling (for larger data lists), live search, and dynamic data rendering.

How to use it:

1. Load the Virtual Select’s JavaScript and CSS files in the HTML document.

<link rel="stylesheet" href="dist/virtual-select.min.css" />
<script src="dist/virtual-select.min.js"></script>

2. Create a container to hold the virtual select.

<div id="example-select"></div>

3. Define your own options for the virtual select.

myOptions = [
  { label: 'Options 1', value: '1', alias: 'custom label for search' },
  { label: 'Options 2', value: '2', description: 'custom description for label'},
  { label: 'Options 3', value: '3' },
  ...
  { label: 'Options 100000', value: '100000' },
],

4. Initialize the Virtual Select library and done.

VirtualSelect.init({
  ele: '#example-select',
  options: myOptions
});

5. You can also directly initialize the library on the native select element.

<select multiple name="native-select" placeholder="Native Select" data-search="false" data-silent-initial-value-set="true">
  <option value="1" disabled>Option 1</option>
  <option value="2">Option 2</option>
  <option value="3" selected>Option 3</option>
  ...
</select>

VirtualSelect.init({ 
  ele: 'select' 
});

6. Enable the multi select support.

VirtualSelect.init({
  ele: '#example-select',
  options: myOptions,
  multiple: true
});

7. Enable the live search support.

VirtualSelect.init({
  ele: '#example-select',
  options: myOptions,
  search: true
});

8. Customize the placeholder text.

VirtualSelect.init({
  ele: '#example-select',
  options: myOptions,
  placeholder: 'Select options here'
});

9. Define an array of disabled options.

VirtualSelect.init({
  ele: '#example-select',
  options: myOptions,
  disabledOptions: [1, 1000, 10000]
});

10. Determine whether to hide the clear button.

VirtualSelect.init({
  ele: '#example-select',
  options: myOptions,
  hideClearButton: true
});

11. More configuration options.

VirtualSelect.init({
