Tips for choosing multiple values from a dropdown menu in Bootstrap CSS version 3

I'm looking to implement a way to select multiple values from a dropdown menu without using the CTRL key. Currently, I am utilizing Bootstrap CSS for styling.

Here is the code for my dropdown:

  <select multiple class="dropdown-menu">
        <option value="monday">Monday</option>
        <option value="tuesday">Tuesday</option>
        <option value="wednesday">Wednesday</option>
        <option value="thursday">Thursday</option>
        <option value="friday">Friday</option>
        <option value="saturday">Saturday</option>
        <option value="sunday">Sunday</option>
    </select>

Is it possible to select multiple values without using the CTRL key with the help of jQuery or JavaScript?

Additionally, I would like to limit the selection to not more than two or three values. Is this feasible?

Thank you in advance for your assistance.

Answer №1

Here is a method to achieve multi-select without needing to use ctrl click.

$('option').mousedown(function(e) {
e.preventDefault();

$(this).prop('selected', $(this).prop('selected') ? false : true);

alert($("#mySelect :selected").length);//select option selected count
//if($("#mySelect :selected").length==2)
//some stuff
   
return false;
});
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<select multiple="multiple" id="mySelect">
    <option id="1">Option</option>
    <option id="2">Option</option>
    <option id="3">Option</option>
    <option id="4">Option</option>
</select>
