How do I remove UL on wp_nav_menu?

Question

I search on this site and found many answers for this question. Most of them is not working on my theme.

Here is a one solution I found and it's working according to my need.

function wp_nav_menu_no_ul()
{
    $options = array(
        'echo' => false,
        'container' => false,
        'theme_location' => 'primary'
    );

    $menu = wp_nav_menu($options);
    echo preg_replace(array(
        '#^<ul[^>]*>#',
        '#</ul>$#'
    ), '', $menu);

}

This code will remove ul at beginning and the end of wp_nav_menu(). So in my theme I just write

<ul class="primary-nav">
<?php  wp_nav_menu_no_ul(); ?>
</ul>

But the problem is coming again when I do not add or activate any menu via admin. http://domain.com/wp-admin/nav-menus.php

Question :

How do I remove the <div><ul>**</ul></div> whether the menu is active or not. Let me know

---

Finally I got it worked :) functions.php

function wp_nav_menu_no_ul()
{
    $options = array(
        'echo' => false,
        'container' => false,
        'theme_location' => 'primary',
        'fallback_cb'=> 'default_page_menu'
    );

    $menu = wp_nav_menu($options);
    echo preg_replace(array(
        '#^<ul[^>]*>#',
        '#</ul>$#'
    ), '', $menu);

}

function default_page_menu() {
   wp_list_pages('title_li=');
} 

header.php

<ul class="primary-nav">
<?php  wp_nav_menu_no_ul(); ?>
</ul>

Answer 1

The function wp_nav_menu takes an argument of fallback_cb which is the name of the function to run if the menu doesn't exist. so change you code to something like this:

function wp_nav_menu_no_ul()
{
    $options = array(
        'echo' => false,
        'container' => false,
        'theme_location' => 'primary',
        'fallback_cb'=> 'fall_back_menu'
    );

    $menu = wp_nav_menu($options);
    echo preg_replace(array(
        '#^<ul[^>]*>#',
        '#</ul>$#'
    ), '', $menu);

}

function fall_back_menu(){
    return;
}

you can even remove the container from the menu and do other stuff with some more arguments sent to the wp_nav_menu function

Hope this helps.

Actually, Wordpress supports this by default:

wp_nav_menu(array(
    'items_wrap' => '%3$s'
));

The default for items_wrap is <ul id=\"%1$s\" class=\"%2$s\">%3$s</ul>.
