I want to add the postlist in this plugin. How can i do this

I am not absolutely sure what you are asking.

I do not have the bandwith to help you setup everything, this is a free plugin ??

You can start with the documentation found on https://www.wpfrontier.com, start looking at shortcodes:

Generally this forum is for reporting bugs, but if you have specific questions I will try to help

Please take a look of youtube playlist.
Then you will better understand. what i want to do.

Here user can create there own playlist. and categories are fixed by the youtube..
My postlist is similar to the youtube playlist.
Please help….

Hiii finnj.

You have not answered my question.. Please help

As i said before, i am sorry but I do not have the bandwith to this kind of support – I wish I had the time

This is a gree plugin, that i do and support in my spare time

ohhh….
Can you please tell me about the monetization of the post.
This plugin have a filter of the abusing etc.
Like when any user post from the frontend this post will be filtered by out list of abusing keyword and if any of abusing keyword exist in the post content( Heading + Post Content ) then this post status will be gone to pending.

Can you please help me ?

You can implement additional validations, but it will require coding and wordpress filters/actions.

There is a simple example here: https://wpfrontier.com/frontier-post-actions-hooks/

Again this example is provided as inspiration and require coding skills, I can not support this, sorry

// This goes into functions.php
// check if categories are empty or only contains default category - if so set status to draft and issue a warning message
function fp_cat_validation($tmp_post, $tmp_task_new, $_POST )
  {
    $tmp_cat = array_key_exists('post_category', $tmp_post) ? $tmp_post['post_category'] : array();
  if (count($tmp_cat) == 0)
    {
    $tmp_post['post_status'] = 'draft';
    frontier_post_set_msg("Warning: Category is empty, please select category - Status set to draft");

    }

  if (count($tmp_cat) == 1 && $tmp_cat[0] == get_option("default_category"))
    {
    $tmp_post['post_status'] = 'draft';
    frontier_post_set_msg("Warning: Category is set to: ".get_cat_name(get_option("default_category")).", please select category - Status set to draft");

    }
  return $tmp_post;
  }
add_filter('frontier_post_pre_update', 'fp_cat_validation',10,3);
