For the calendar widget (Mendix Marketplace - Calendar) I'm trying to make a selector for time in the newedit popuppage, but the widget does not seem to take any form of input for setting time (besides clicking the timeframe or dragging it to a timeframe).Also the timeframes are in hours where I would like them to be in 15 minutes. Is there any way for me to achieve this and what would be the best approach to do so?
