normally only possible in woocommerce...
but if you make a page that is your category in hte block editor and add a posts carousel block in here with hte category you get ot have a featured image on the page...so get a featured image for your 'category' page....

i think there may be plugins that can do this if you don't want to use the block editor...but the official support is going to run out at the end of teh year for the classic editor so learning hte block editor as soon as possible is a good idea.....

Hi
This will help Adding new Category to the main menu to show all posts in that new category Please let us know how you get on

you can add the category to the menu and when clicked on then it will show all the posts in that category...
don't forget to go into posts>>categories and edit the category...add a description to add more content to that page.....it helps a little with seo.....
have fun

Hi
Log into your backoffice and try
Appearance customizer header
And then see if you can delete
Let us know how you get on

I believe many themes require you to purchase their "premium theme" before you can edit or delete it.

why would you want a page without a title.....
are you looking to create a landing page ....
if so then the block editor is the best choice for that....
to see if it is enables goto settings>>writing and choose allow user to switch ....
then create a page and down the right will be switch to block editor....
you can now use all of the precreated blocks and other elements to create your page..
good luck
