You need to copy existing and customize, example:
Also additional changes required in edit page:
First you should add new field via your administration:
Admin->Real estate->Fields (You can see # part there, what is field ID)
Then you should add it to your template file property.php
{estate_data_option_#}
Where # represents field id / key of option
You can also use alternative PHP syntax, for example:
<?php if(!empty($estate_data_option_#))echo $estate_data_option_#; ?>
More details are available in documentation:

To add new category, most simple way is to just copy example code from another category and modify by your needs.
Or use this code example:
<?php $category_id = 1; ?> <?php if(isset(${"category_options_$category_id"}) && ${"category_options_count_$category_id"}>0): ?> <h3 class="page-header"><?php echo ${"options_name_$category_id"} ?></h3> <div class="property-amenities clearfix"> <ul> <?php foreach(${"category_options_$category_id"} as $key=>$row): ?> <?php if(!empty($row['option_value'])): ?> <?php if(count($row['is_text']) > 0): ?> <div class="panel-row"> <p class="bottom-border"><strong><?php _che($row['option_name']); ?>:</strong> <span><?php echo _che($row['option_prefix']); ?> <?php echo _che($row['option_value']); ?> <?php echo _che($row['option_suffix']); ?></span><br style="clear: both;" /></p> </div> <?php elseif(count($row['is_dropdown']) > 0): ?> <div class="panel-row"> <p class="bottom-border"><strong><?php _che($row['option_name']); ?>:</strong> <span class="label label-success"><?php echo _che($row['option_prefix']); ?> <?php echo _che($row['option_value']); ?> <?php echo _che($row['option_suffix']); ?></span><br style="clear: both;" /></p> </div> <?php endif; ?> <?php endif; ?> <?php endforeach; ?> </ul> </div><!-- /.property-amenities --> <?php endif; ?>
