How can I see backend of Eshop

Hello, I would like to buy Your Eshop extension and want to somehow see the backend part, 
Especially how are options organized.
And if I buy template should I pay additionally for it?
And one more question for Joomla 3 an Joomla 4 is the same extension or not.
Thanks in advance.

Hello Mariam,

Thank you for interesting in our EShop Shopping Cart extension and submitting the ticket here. Regarding your questions:

1. We don't give the access to the demo of back-end side of our EShop Shopping Cart extension. Options manager section and assign options to product is easy to use.

2. Yes, the template and extension are 2 separated packages. You need to purchase both of them if you want to use the template too.

3. There is only one extension / package of EShop which is compatible with both of Joomla 3 and Joomla 4. So you can use it on both of Joomla 3 and Joomla 4 as you want.

If you have any other questions, don't hesitate to let me know.

Sincerely, Giang

Thank You for Your answer. I have other ones.
If filter form could be different for different categories?
And if I install extension will sample data inserts as well.
Can I make rewritings from joomla administrator part?

Hello Mariam,

That's no problem. Regarding your new questions:

1. Yes, when you select a specific category in filter form, then the form will be changed for that category. Only attributes, options, etc available for that category are displayed.

2. Yes, you can add the sample data anytime as you want.

3. Yes, EShop allows you to override the layouts from the template easily. You can also add the custom CSS from the back-end side easily.

If you have any other questions, don't hesitate to let me know.

Sincerely, Giang

Thanks a lot for previous answer. I noticed there aren't anywhere mentioned about multilanguageness.
And if I install joomla 3 version of Your component after update can it be converted to joomla 4 without any lose?

Hello Mariam,

That's no problem.

1. You can read about the multilingual in EShop here: eshopdocs.joomservices.com/multilingual/eshop-multilingual

2. Yes, anytime you can update Joomla from version 3 to version 4 and EShop to the latest version without losing anything.

If you have any other questions, don't hesitate to let me know.
