Template override to remove WooCommerce Bookings resource cost indicator from dropdown select

select.php

<?php
extract( $field );
<p class="form-field form-field-wide <?php echo implode( ' ', $class ); ?>">
	<label for="<?php echo $name; ?>"><?php echo $label; ?>:</label>
	<select name="<?php echo $name; ?>" id="<?php echo $name; ?>">
		<?php foreach ( $options as $key => $value ) : ?>
		<?php
		/*
		 The default file just echos out the value
		 this will modify that behaviour to match a pattern and replace that pattern with an empty string
		 it is echoed out below via preg_replace
		*/
			$pattern = '#\(\+<span class="amount">.*\)#';
			$replacement = '';
		?>
			<option value="<?php echo $key; ?>"><?php echo preg_replace( $pattern, $replacement, $value ); ?></option>
		<?php endforeach; ?>
	</select>
</p>

There is a filter called "woocommerce_bookings_resource_additional_cost_string" that allows to modify the string. Over writing the whole template removes the price from all "other" fields that use the type select. If that is the goal, this is the quickest way to change all outputs no matter the source (plugin).
