Magento 2 form mini filter where category ID in array

I am trying to use the following method to filter the category id on my mini form submit

<input type="hidden" name="cat" value="1">

But this only allows to filter by 1 category id, I need to be able to pass in an array of category ID's to the mini form. Is there anyway I can use a similar method to filter the search results by an array of category id's? Or can anyone point me in the right direction on how to achieve this?

You can use serialize() and base64_encode().

$cat_ids = array(1, 2, 3);
$post_cat_ids = base64_encode(serialize($cat_ids));

// Input field
<input type="hidden" name="cat" value="<?php echo $post_cat_ids; ?>">

On server side you can get back array:

$cat_ids = unserialize(base64_decode($_POST['cat']));
print_r($cat_ids);
