We would like to create a chatbot for the SAP Community, but want people to select from a large list, but there are too many to choose from a list control, so we want to use/create a control that lets people type in a few letters and the control will guide them to the right tag, just like is done for example in the community when someone selects a tag for a blog or question.

Is there such a control? Can we create our own custom control?
