OK now I see – yes this was the HTML block where I attempted to place the search box. It works on the page now, but it will not work in the Flatsome menu structure…
Under Appearance > Customize you can access the layout options. Mouse over the header menu, for example and you should be able to select any of the elements to bring up the layout editor. In there I’ve tried Blocks and the HTML widget, both of which support short codes. Here is the shortcode I had in there:
[wd_asp elements='search,settings,results' ratio='30%,70%,100%' id=1]
This won’t work, despite working fine on the page itself.
