How to make the calendar popup on click of a calendar icon ?

Question

I am working on the website in which I want to popup the calendar on hitting calendar icon.

The HTML code which I have used in order to place Start Date

Answer 1

It looks like you are using jQuery's datepicker?

You are trying to execute this line

$( "#datepicker" ).datepicker();

but you don't have any element with an id datepicker.

Try adding the id datepicker to your input if you want the entire input to change into datepicker on click. Added id datepicker to your input with the class start_date.
