How to correctly name this in English (in an official documentation for IT system):
Should I name this:
- a listbox,
- a list box,
- a list-box,
- a combobox,
- a combo box,
- a combo-box,
- a dropdown,
- a dropdown list,
- a dropdown-list,
- a drop down list,
- a drop-down-list,
- other name.
Similar question resulted with an answer that form with space is much more popular and often used.
Simiral Google Ngram search reveals that:
- "listbox" is most popular,
- "dropdown", "dropdown list" and "combo box" are less popular, but usage is still significant,
- usage of all others falls below significance level.
It seems that "listbox" more popular than "dropdown" and "dropdown list", but this still doesn't answer my question, as I don't know, if "listbox" can be used correctly for pictured element?
