Hi Alexander,
First of all, thanks for you help…
I’ve search but it’s bizarre. I can’t change now manually the url since last wix update (with codes)…The URL is in english and before it was in french. ( page-d-articles and now product-page ). Doesn’t matter. just few weeks and SEO will be ok (301 page setup)
Last question and then i’ll don’t ask nothing 
i’ve 5 premium wix sites…I’ve searched 1 week, seen lots of videos ,tutorials and forums but i can’t have the good code to do a simple thing:
I’ve a repeater (items form an input formulary) and i want to make a dropdown menu with the categories (ex: Cities form the database). Just click on the category and only see the items on the repeater…A lot of codes on youtube but nothing simple to help me…Can you just send me simple code that i can use for this function ? Is there a possibility to display only 10 items on the repeater and force the visitor to push “second page” ? Thanks for your help…Sorry for my english…i’m a french living in Spain
