Newbie asking how to output choices from a select field

I’ve been hunting for answers on this in the documentation and forums but nothing I try seems to work for me.

I have a group of fields, let’s call it Field Group;
Among the fields is a Select item, let’s call it Category (slug: category);
The Category has three entries, let’s call them Category 1, Category 2, Category 3;

I want to create buttons out of those categories that will display in the front end, ultimately they will determine what is displayed from a custom post type using WP_Query. At the moment my WP_Query just displays all of the posts from that custom post type which is a bit disorganised.

In quite a few of the examples it mentions ‘repeater’ but I have no idea what that is or how it relates to my fields or code.

So, after much mucking about and trying various things this is what I have at the moment, I get nothing output to the front end:

<div class="category-buttons">
        
            <?php 

                if( have_rows('repeater') ): 
                    while( have_rows('repeater') ): the_row();
                    $select = get_sub_field_object('select');
                    $value = $select['value'];

                    ?>
                    <ul>
                        <?php 
                        foreach ($select['category'] as $active => $button) :
                        ?>

                        <li <?php echo ($active === $value) ? 'class="selected"' : '' ?>>
                            <?php echo $button; ?>
                        </li>

                        <?php endforeach; ?>
                
                    </ul>
                <?php endwhile; 
            endif; ?>
    </div>

I get the feeling I’m missing something really simple, I’m fairly sure ‘repeater’ shouldn’t be in my code but I don’t know what should be there in it’s place. Hope you can help!
