This can be achieved esily using a custom template.

I created a php file in the templates folder and replaced the select and option codes with ul and li And I used this variable to display it : [catlist id=1 template=mydefault]

But it doesn't work for me The codes in the mydefault.php file:

<?php
/* List category posts template for displaying posts indexed by child categories.
 *
 * Based on https://gist.github.com/klemens-st/e46ae830e42fb7a200306cfaa87ba18a
 *
 * Most of the code is self-explanatory. The elements specific to this template
 * you might want to customize are:
 * - line 93: sorts the array of child categories (not the posts themselves) alphabetically
 * - line 95: the html of child categories' sub-headings
 *
 * In order for this template to work as expected you must use
 * a shortcode with only one category specified, this category must be
 * the parent category of the child categories you want to list. Example:
 *
 * [catlist name="My Parent Category" template=child-categories]
 *
 * Additionally, it will only work if the posts have only one category and it is
 * a child category of the parent specified in the shortcode. Feel free to expand
 * the code to make it more versatile.
 */

// Parent category id.
$parent_id = intval( $this->catlist->get_category_id() );

//This is the string which will gather all the information.
$lcp_display_output = '';
// Show category link:
$lcp_display_output .= $this->get_category_link('strong');
// Show the conditional title:
$lcp_display_output .= $this->get_conditional_title();
//Add 'starting' tag.
$lcp_display_output .= $this->open_outer_tag('div', 'lcp_catlist');
// An array with post strings indexed by Child category.
$index = [];

global $post;
while ( have_posts() ):
  the_post();

  $category = get_the_category()[0];

  // Check if protected post should be displayed
  if (!$this->check_show_protected($post)) continue;

  // Drop the post if it's not assigned a child category.
  if ( $category->parent !== $parent_id ) continue;

  //Start a List Item for each post:

You used an example template that is meant to be used with posts that have a child category assigned.

You should start from the default template as the documentation suggests.

Thanks for your help, part of the problem is solved :) Now it displays the title in the select field, but when I choose one of them, it does not enter the page of that post. The codes are as follows and there is no <a> tag in it

<select class="lcp_catlist" id="lcp_instance_0">
<option>Little Krishna</option>
<option>Clash Royale</option>
<option class="current">Clash of Clans</option>
</select>

I am new and not familiar with WordPress variables I can't work with php either I would be grateful if you could tell me how to do this. I changed the codes as follows:

So you have your <select> dropdown working but now you want the browser to navigate to the post you select. This plugin cannot help with that because its only role is to generate a list of posts.

To complete your task you have to add some Javascript code that will get the URL from the plugin's output and navigate to that URL.

picandocodigo / List-Category-Posts

Put the link of the posts inside the select id tag #494
