Hi @sunsoftpk,
Could you please try the following snippet and then see whether that helps?
<?php
add_filter( 'forminator_field_single_markup', function( $html, $element_id ){
static $select_id;
if( false !== strpos( $element_id, 'select-') && preg_match( '/select-([\d]+)-field/', $element_id, $matches ) ){
if( $select_id ){
$select_id += 1;
$html = str_replace( $element_id, "select-$select_id-field", $html );
}else{
$select_id = intval( $matches[1] );
}
$select_id ++;
}
return $html;
}, 10, 2 );
The above code can be added as a mu-plugins. Please check this link on how to implement the above code as a mu-plugins:
