Church 4.0 Theme options- select tags vice categories

[Chelle]

I've manage to implement this on 3.0 version of Church. I'm now trying my hand at doing the same thing for version 4.0. I've probably stared too long at the theme-options.php because I'm not connecting my dots.

Here's the working code for the Church 3.0 version I edited for my site www.sansdreamscape.net

        case 'tag_select':
        option_wrapper_header($value);
        $tags = get_tags();
        ?>
                <select style="width:240px;" name="<?php echo $value['id']; ?>" id="<?php echo $value['id']; ?>">
                    <?php foreach ($tags as $tag) {
                    if ( get_settings( $value['id'] ) == $tag->term_id) { $selected = ' selected="selected"'; } else { $selected = ''; }
                    $opt = '<option value="' . $tag->term_id . '"' . $selected . '>' . $tag->name . '</option>';
                    echo $opt; } ?>
                </select>
        <?php
        option_wrapper_footer($value);
        break;
        //end tag select code
        //////////////////////////

Implementation for version 4.0 is quite different, and I'm having a hard time matching terms to understand what data is expected where. Can I get a breakdown of the arguments used in the dropdown_cats function [i.e. get_theme_mod('featured_top_left') etc], so I can try and make the tag select dropdown example provided on the get_the_tags() ref page work..

<?php wp_dropdown_categories(array('selected' => get_theme_mod('featured_top_left'), 'name' => $settings.'[featured_top_left]' )); ?>

Right now all I'm seeing is I define a tag dropdown function..and call it, and that's when my brain stops working with me
