Thanks. I have done it.

Is this possible that a customer can access to their panel after registration, but can't see the price or buy anything without verification? Because I'm using ShowPriceAfterLogin plugin.

Thanks @ghermans
But this will change for all. I want different session lifetime for different auth type.
[Like, for admin SESSION_LIFETIME=20 & for customer SESSION_LIFETIME=10]

How to set individual SESSION_LIFETIME for admin panel & customer panel?

I have four table countries, states, districts, upozillas. If I select a country state option need to be updated, the if I select a state then district need to be updated and go on.

I found a way in customer panel's address section. But I want to do it on my own package & in multiple options.

I extended Product Module. Where should I change, so that product filter use my ImageFilter instead of Webkul's ImageFilter?

How can I remove billing details completely from from checkout page?
Or swap them?

Only State code showing in customer/address page. Isn't it obvious that the default_name of state would show like country?

For country
public function country_name($code)
{
$country = $this->countryRepository->findOneByField('code', $code);

    return $country ? $country->name : '';
}

For state ?

Solved thanks
