Drupal 8.x

I am building a ecommerce using Drupal 8 Commerce.

I want to set product paths like this pattern:

domain.com/smartphones/samsung-galaxy-s9

domain.com/ar/smartphones/samsung-galaxy-s9

So, I used this pattern for English language

[commerce_product:field_category:entity:name]/[commerce_product:title]

I have installed a new Drupal 8 website.

Activated css, js aggregation.

Cleared the cache.

When accessing the website, css files are aggregated, but javascript files didn't.

The css references: minified

Trying to build a my first D8 website after building many D6 and D7 sites.

I'm trying to use bootstrap 8x-3.11 as I use bootstrap with D7 sites 

I'm not able to select different themes as I did with D7, am I missing something in D8?

D7 has a list of Themes

D8 has Bootstrap (default) only.

jsDelivr 3.3.7

Hello everyone.

I have followed this video Here to try and make a menu tab as shown in the video, i followed the video by the letter and it just will not work!

here is the results after i create the view https://ibb.co/hip3xJ
i just don't understand why the tabs won't show up! i made sure to 100% follow the video and the results is always like this no matter how many times i try to create it!

I want to create a list which will contain country name and it will be populated from a database. How can i achieve this?

What I'm seeing is basically no CSS for the galleries, so it looks all screwed up. JavaScript functions such as clicking on thumbnails aren't existing or don't work - if I click on a thumbnail nothing happens. Some scripts I can change the main image by clicking on the thumbnails and even shows a slide animation, but it's still awfully formatted and still seems broken.
