Hi,
the whole list stuff is added to the descriptopn and coded in the generic_cb and there is no way to easily change that.
For the 3.x version the list en tekst fields are removed, here the idea is that you create the list on your own. The same method can be used on the 2.5 version.
Assign the 'old price' to one of the Select fields for example Select8
now in the layout use
Code:
echo '<span class="oldprice">Old price: '.$item['Select8'].'</span>';
or whatever you like
or use CSS with the current list
Code:
.datafeeds_description li:nth-child(3) {
text-decoration: line-through;
}
