[Checkbox LVGL] How to select only ONE case on several choice

Hello everyone,

For a project on a DisplayTouch I need to dispay 4 cases (Which I did and works well) but I would like to be able to select only one case and being obliged to deselect it to select another one. I don't find the right fonction for that.

Did someone meet the same issue ?

Thank you

switch () { case ... }
