remove empty option from bootstrap select javascript

To remove the empty option from a Bootstrap select element using JavaScript, you can use the following code:

document.addEventListener("DOMContentLoaded", function() {
  var selectElement = document.getElementById("mySelect");
  var firstOption = selectElement.options[0];

  if (firstOption.value === "") {
    selectElement.removeChild(firstOption);
  }
});

In this code, we first wait for the DOM to be fully loaded by adding an event listener to the DOMContentLoaded event. Then, we retrieve the select element by its ID using getElementById(). We access the first option using the options property of the select element and remove it from the select element using removeChild() if its value is an empty string.

Make sure to replace "mySelect" with the actual ID of your select element in the code above.

This code will remove the empty option from the Bootstrap select element using JavaScript.
