Bootstrap-multiselect is very slow with a large pool of options

like below fixes the issue We had exactly the same problem, but really wanted to keep the component as it is so convenient.
Our solution was render the component with no options, then use setTimeout to load the options AFTER the page has rendered. This stopped the options rendering from holding up the whole page.

<select id="sites" class="form-control" multiple="multiple">
    <option value="1">Site 1</option>
    <option value="2">Site 2</option>

This might help you What you are seeing is the first render of the DOM being slow. Take this code:
code :
let html = '<select multiple>'
for (var x = 0; x < 500; x += 1) {
  html += `<option value=${x} selected>${x}</option>`
}
html += '</select>'

var startTime=new Date().getTime();

document.getElementById('container').innerHTML = html;

alert(new Date().getTime() - startTime)
class Select extends React.Component {
  constructor (props) {
    super(props)
    this.state = {}
    this.state.selected = props.selected
  }
  handleClick () {
    this.setState({selected: !this.state.selected})
  }
  render () {
    const val = this.props.value
    const selected = this.state.selected
    return (
      <li onClick={this.handleClick.bind(this)} className={selected ? 'selected' : ''}>
        {val}
      </li>
    )
  }
}

const Hello = ({list, defaultList}) => 
  <ul>
    {list.map(item =>
      <Select key={item} value={item} selected={defaultList.indexOf(item) !== -1}/>)}
  </ul>

With these it helps I want to write JQuery code that will uncheck and deselect some options from Bootstrap Multi select. , In MultiSelect to select options you need to use
code :
$('#example-optionClass').multiselect('select', ['2', '6']);
$('#example-optionClass').multiselect('deselect', ['1', '4']);

help you fix your problem I'm using Bootstrap Multiselect (https://github.com/davidstutz/bootstrap-multiselect). It's a great component but i'm having the issue described below. , What if you use an array of values instead?
code :
$('#select-status').multiselect('select', ['1', '2', '3']);
