I have found 1 solution from internet. You can double check at this link or below:
In administrator/components/com_virtuemart/classes/ps_product_category.php
/*
* Returns an array of the categories ids recursively for a given category
* untreeCat copy lashae (virtuemart forum http://virtuemart.net/index.php?option=com_smf&Itemid=71&topic=20837.0)
* @param int $kat
* @param int $container
* rewritten by haselnuss (to use ps_DB class and store the function in ps_product_category.php)
*/
function untreeCat($kat, &$container) {
$db = new ps_DB;
$q = "SELECT category_child_id FROM #__{vm}_category_xref WHERE category_parent_id='$kat'";
$db->query($q);
// if it is a leaf (no data underneath it) then return
if (!$db->num_rows()) {
return;
}
//else append the result, and recurse the function (so to speak)
else
{
while($db->next_record()) {
$container[] = $db->f("category_child_id");
$kat = $db->f("category_child_id");
$this->untreeCat($kat, $container);
}
}
}
and in administrator/components/com_virtuemart/html/shop_browse_queries.phpAbout line 63 change:
// Filter Products by Category

}
}

When I started web development, the stability of open source was still a question mark and developers were discussing whether ASP or PHP was more powerful.
JavaScript was always popular but never as this much. And every new day makes it more popular and required.
To me, words like CodeIgniter, Zend, MooTools or jQuery sounded like totally new languages and didn't know why to use them when I already can do anything I want.
Within time, you start re-coding stuff like a contact form, an e-mail validation pattern ,etc.
While building something, I used to say "I had seen something nice that would fit here but can't remember the URL". Pretty sure, you live that too.
If you design a website in an image editing application (like Photoshop) and it gets too much time of yours to make it look good, then you may be missing the tricks as they are the one that makes the difference.
Many developers don't like ready-to-use codes but prefer to build everything from scratch. That has a reason: "it is usually harder to learn another system compared to building your own".
Even if you are not an expert in a field, writing about a subject helps improving yourself so much.
I'm pretty sure every web designer/developer has a great project in mind for months/years but couldn't bring it to life because of the client projects.
