Calendar in

Dear friends,

I already bought BrightBox from your company few years ago.
But, I am considering to buy ENFOLD theme to use for my business of travel agent.

I would like to use Product (or Portfolio) for each tour product. (e.g., ‘Highlights of Seoul Tour’ -> described in a Product, or Portfolio.)
Therefore, I need to ask you few things before buying this theme.

1) Under following menu,
ENFOLD2017 demo > Shop > Product Examples > Default Product

There are only two tabs; Descriptions, Reviews.

But, I would like to add more tab(s) such as Schedule, Prices….is this possible?

1) Under following menu,
Other demos > E-commerce > ENFOLD Hotel Demo > Rooms > One Bedroom Suite

Here, I can see the calendar.
Is this calendar is plug-in, or your native element?

Please advise me regarding above questions.
Then, I will have more interest in buying your great theme.
