Hello Mohannad,
Welcome to the OutSystems Agile Network forums

If I understood you want to display sub categories from a main category selected. You need to use onchange property for first combo box, so add an action that will populates second combo box depending on first category selected. Check my oml in attach for an better understanding.
I hope that helps
