I'm studying on how to use bootstrap datepicker but i need it to show only the months or year just like this:

but the result only became like this:
I only need to pick the month and the year not the whole calendar. Below is my whole code snippet:
$(document).ready(() => {
$("#datepicker").datepicker( {
format: "mm-yyyy",
startView: "months",
minViewMode: "months"
});
})
<html lang="en">
<head>
<meta charset="UTF-8" />
