Hi Alex,

as my :before rule is a little bit more complex StylesFilter is not the way I really like.

Is there a way to implement a custom function getMyOwnValues(), which I can include like this:

oxy_editor(

            type, popupSelection,

            edit, "@attribute",

            values, getMyOwnValues(),

            labels, getMyOwnValues(),

            resultSeparator, "|",

            columns, 10,

            selectionMode, "multiple",

            fontInherit, true);

Thanks for your support

Markus
