Module Class Suffix when Module lacks the parameter? - Joomla! Forum - community, help and support

hi:

i know saw somewhere months ago, can not find in search of forums.  many modules in extensions area not have parameter module class suffix can assigned, rendering extensions difficult customize.

how add module class suffix module not set one?  ie, how add parameter module's php can assign module class suffix?

thanks in advance.

i may have figured out, share everyone--and if wrong can tell me.

it appears if person goes module xml file , adds such in area work.

code: select all

<param name="moduleclass_sfx" type="text" default="" label="module class suffix" description="a suffix applied css class of module (table.moduletable), allows individual module styling" />   

at same time, appears nothing needs inserted in php file or anywhere else.  tried xml modification , appeared work on test server.
