I'm not sure what exactly you mean? If you want to know how to mix php and html code, it's done the following way:
PHP Code:
<?php
echo "php code here<br />";
?>
<strong>html code is bold</strong><br />
<?php
echo "another php line<br />";
?>
If you want to know how a component can be coded, please take a look into the developers manual, which can be downloaded from the 4.5.1 downloads section at
