How to set the font size of a listbox

Anyone can help me to point out setting.
How can I set the font size of a listbox shown in the red square of an attached picture?

Thank you very much in advance,
With my most sincere,


Hi @chimmy you can register your css file(s) in your add-on and give them precedence over SENAITE’s. A css with something like below should be enough:

.cg-autocomplete .cg-DivItem {
    font-size: 2em;

In case you don’t have an add-on, you can directly add your own styling via ZMI. See:
