The circle genlist is great for selecting from a list of items like for example contacts. If the list is huge though navigation gets a little cumbersome. There is a feature called fast rotary action to solve this problem. But according to the linked documentation it's not available in a Tizen native API app.
What is the best way to implement quick navigation in a huge circle genlist in a Tizen native API app? Do I have to come up with something myself like an upstream A-Z list to link into the circle genlist or is there some recommended way of doing it?
fast rotary action is not supported in native application for now.
if you want to implement fast navigation with rotary events, you can manually call
elm_genlist_item_bring_in(Elm_Object_Item *item, Elm_Genlist_Scrollto_Type *type)
to bring item in the viewport, with handling the provided rotary event.
see more about rotary events, https://docs.tizen.org/application/native/guides/ui/efl/rotary-events/
Thank you.
