Close Off-Canvas on click of a button

close-offcanvas.txt

1. Add a custom class to the Button on which you want to close the off-canvas.
Refer - https://cl.ly/f61014b8265b

2. Paste below code in your active Themes Functions.php file - 
function offcanvas_custom_script() {
	?>
		<script type="text/javascript">
			jQuery(function($) {
				$( '.custom-close-offcanvas' ).click( function () {
					var $canvas = $( '.uael-offcanvas-show' ).attr( 'id' );
					$canvas_id = $canvas.substring( $canvas.indexOf('-') + 1 );
					OffCanvas._close( $canvas_id );
				});
			});
		</script>
	<?php
}
add_action( 'wp_footer', 'offcanvas_custom_script' );

Note - In the above code the "custom-close-offcanvas" will be replaced by the custom class you will add to the button.
