How to submit Opportunity?

I have have created one Opportunity.
From opportunity created one quotation.
There is two option for opportunity, one is for quotation and other is for opportunity lost i.e. close opportunity.

How to submit opportunity into success state?

Opportunity is not submittable anymore.

You should pull your pre-sales emails into Opportunity.

Sorry, I doesn’t understand. If we create quotation from opportunity then it should be close.
Opportunity has currently lost option but there is no close/success option.
