Inquiry about some features

Hi

I tried your demo I would like to ask if the followings features are available:

Minimum order amount for both delivery and collection

Option validation, when there is a long list of options let’s say about 4 or 5 sections of options in one item and all are required, if the customer click on add to cart button without selecting any option, would the list scroll up for validation to notify the customer about the error?

Does the plugin have conditional logic for the option? For example 3 option radio buttons: on it’s own, Small meal and Large meal. Each option has different option.

Do you provide admin demo?

Thanks for your answer in advanced my friend.
