Hi Petro, You can create a custom drop-down, but it would have to be in one of the tabs in the lower right, such as Video, Audio, or a new tab. You can't create a custom control next to the Format and Preset drop-downs in the top-right. So if it is feasible, it would be ideal for you to use the existing Preset drop-down in the top-right, next to the Format drop-down. But if your exporter has a special need, you can create a custom drop-down. It sounds like you're already doing it, basically. Just as the SDK sample exporter does during exSelGenerateDefaultParams, you could call AddParamGroup() with a name like "Preset", and then create the drop-down param similar to how the SDK exporter calls AddParam() to create the field type param, which is a drop-down with multiple selections.
