Hi @ocio132
I’m really sorry, but the “Search” element does not have an option to be placed inside the mobile menu.
For the mobile menu, we do offer a “Search Box” – https://creativethemes.com/blocksy/docs/header-elements/search-box/ – element in Blocksy Pro, but you might need to upgrade your package to get access to this feature.
Hope this clears things up!
Thanks.
