Hello,
I would like to get my navigation the same as below, mouse over jewellery - and you get a drop down to select jewellery by brand, price, category etc. Please see example Below.

This is my jewellery page, https://www.mozerisfineantiques.com/jewellery - I have already purchased universal filter for squarespace and have the option on my page to filter the products by brand, price, etc, I just need the same option when using the navigation.
--------------------
I would also like to add this into my header
https://ibb.co/yNkF5bz
language change, and a small magnifying glass. I know you can add the search bar, but I would just like a small magnifying glass next to my social links on the home page:
www.mozerisfineantiques.com
 
Thank you, much appreciated.

Hello,
This is my website : https://www.mozerisfineantiques.com/
I would like to add video in this style : 
https://www.chanel.com/gb/high-jewellery/
You come on the page and it autoplays the video.
 
On squarespace there is 2 options, add a video normally with youtube link, which requires the visitor to press play and it opens seperate window to play the window.
Second option is add a video block, and on "background" of the section you add the video and it autoplays without having to click play. However, this type of video does not display on mobile phones.
I would like to have it like on the Chanel website, works on mobile, and does not require seperate window to play video.
How can this be achieved?
Thank you.
