How do I hide Categories in my 2 menus

Site URL: https://www.iletaitunefleurartisan.com/shop

Hi

At present, it's not possible to rearrange the order of category listings along the side of the page, as they'll always appear in alphabetical order by default. 
So I added a "—" to separate my travels categories from the accessories.
Then I decided to separate my menu in 2 "filters" to separate in a different way all my travel names (— PARIS).
So i created a "Cloud Tag" by Category in the top and I let the "in this built-in category navigation" on the left.
What I would like to know how to do  is :
- To hide from the left menu all the travel names (—) 
- Keep on my top menu only the travel names (—) 

I also try to reorganize by using "ARCHIVE" my tag (Par mot clé > TAG) and category (Accessoires) --> You can see it on the COULD MENU picture (Top left)
But same problem here, I can't select the categories I'd like to keep.

Thank you ver much for your help!

What is access password?

Also, you can use CSS to reorder all items in category nav

Hi

You will see I tried differents stuff that I let on the shop page.
At the beginning I wanted to have my items available by accessories name (peignes, etc...) and also available by "travel name". Like 2 filters : Accessories and Travels. Then I discovered this "cloud tag" that I find quite cool to place the recherches by "Travels". 
So I'd like to know how to do both css to reorder all items in category nav but also know how to hide some category according the filter I want.
I will try both and choose according the graphic design I like 😉

Other option that I would love to know, is (category nav) :
- Add a space between my accessories ans my travels in order to separate them from each other.

each items has specific order

• Tout: nth-child(1)
• Barrettes: nth-child(2)
• Bracelets: nth-child(3)

to hide an item, add this to Home > design > Custom CSS

/* hide peignes */
ul.ProductList-filter-list>li:nth-child(6) {
    display: none;
}

Thank you! I check this !
