Custom filters based on category`s CPT

I know that this is not possible but 🙂

I created for example 3 fields – 1 2 and 3 in one CPT.

I have 3 categories:
first
second
third

I wanna to show custom field 1 only in first category details page, archive item listing page and add listing page etc.

In details post page, archive item listing page i probably need to use php if else statements:

Something like that

if (first-cat == true){
echo do_shortcode( ‘[gd_post_meta key=”first-filter”]’);
}

or

<?php if (in_category( ‘first’ )) : ?>
[gd_post_meta key=”first”]
<?php endif; ?>

How to make this work in GD?

In add listing page i need probably use javascript like this:

I have select field – categories.

if option 3 (category 3 ) is selected (based on val or text)
then show all divs with class = x3 🙂

Please help me:)
