Hi,
you can use Joomla Template override feature, for example for profile page:
- Copy file from /components/com_jsn/views/profile/tmpl/default_fields.php at /templates/your-theme-folder/html/com_jsn/profile/default_fields.php
- Edit new file and replace HTML structure from DL,DT,DD to UL,LI

Thanks. Thats not what I mean. See please the image the column "Lehrbetrieb" this is a output from a selectlist... the output is not DL, DD.. the output is just the list in plaintext.. and I need to have "ul/li"

Ok, now I have understood, try with these steps:
- Copy file from /components/com_jsn/views/list/tmpl/table_user.php at /templates/your-theme-folder/html/com_jsn/list/table_user.php
- Edit new file and replace all occurrences of

<?php  echo $this->user->getField($field,true); ?>

with this code

<?php if( is_array( $this->user->getValue( $field ) ) ) { echo '<ul><li>'.implode( '</li><li>',$this->user->getValue( $field ) ).'</li></ul>'; } else { echo $this->user->getField( $field, true ); } ?>

Basically if the raw value of the field is an array then it will be displayed like HTML list.

Hi,
sorry for late reply, try with this code:

<?php if( is_array( $this->user->getValue( $field ) ) ) { echo '<ul><li>'.implode( '</li><li>',explode( ',' , $this->user->getField( $field ) ) ).'</li></ul>'; } else { echo $this->user->getField( $field, true ); } ?>
