// Demonstrate dynamic item list + deletion support using the BeginMultiSelect/EndMultiSelect API.
// In order to support Deletion without any glitches you need to:
// - (1) If items are submitted in their own scrolling area, submit contents size SetNextWindowContentSize() ahead of time to prevent one-frame readjustment of scrolling.
// - (2) Items needs to have persistent ID Stack identifier = ID needs to not depends on their index. PushID(index) = KO. PushID(item_id) = OK. This is in order to focus items reliably after a selection.
