Thx a lot for your help it works like a charm 😉
Problem solved.

Thx,

Should i use it this way ?

add_filter(‘wdm_before_fetch_template’,’my_fetch_template’,10,1);

and then

function my_fetch_template($vars) {

$vars['file_list'] = "tag value";

$vars['my_custom_file_list'] = callback_function();

// code to customize how file_list is rendered

return $vars;

}
