I want to use an incomplete sentence to introduce a list of items but I could not find any punctuation guide on this. If I remember correctly, I have seen people using hyphens for it.
Example: If you would like proceed, please indicate-
- whether you are 18 or above;
- whether you have enough deposit in your account; and
- the effective date for the changes.
I would like to know if the hyphen after "indicate" is used correctly. And should I capitalize the first word of each item. Thanks a lot.
Edit: Thank you for your help. However, my confusion here is that, in my example, "please indicate" can be paired up the any of the three items in list to form a complete and independent sentence, e.g. "please indicate whether you are 18 or above."
The example of the usage of colon I saw in the related posts is not quite the same:
There are two types of insects:
(a) white
(b) black
"There are two types of insects white" is not a correct sentence.
