Hi Tony, Right now you cannot control the <Empty> label set of the combo box which allows you to delete the entire attribute. I added an issue on our side and hopefully we'll find a solution for this.

For this element:

<variable name="General_Serif_Font">Arial</variable>

I have this (work-in-progress) Author-mode CSS:

====== variable::before { content: oxy_label(text, "Variable: ", width, 5em) oxy_textfield( edit, '@name', columns, 40 ) oxy_label(text, "Output: ") oxy_combobox( edit, '@output-type', editable, false, values, "web, print-color, print-mono", labels, "Web, Color, Mono", canRemoveValue, true, fontInherit, true

); font-family: 'Arial Unicode MS', 'DejaVu Sans', sans-serif; }

variable { display: block; content: " = " oxy_textfield( edit, '#text', columns, 40 ); visibility:-oxy-collapse-text; background-color: lightblue; } ======

The 'labels' property works, thank you, but how can I provide a label (and, eventually, a tooltip) such that the non-existence of the @output-type attribute shows as 'All', not '<Empty>'?
