All our themes come with a search box as part of the layout. Your clients should not "search for the search", so having the search box right on every page is a plus.
But keeping a streamlined and clean design, like the ones we strive for, while having a search box on every page is tricky, to say the least.
One option, included in some of our themes, is to have a "auto-hideable" search box, like for example on Stephen Alvarez website. Neat, but a bit harder to spot.
Enter our brand new options to customize the search box, via the Advanced panel in the Design part of your admin space, that let you, for example, turn the box into a single underline, and remove the "Go" button.
(To access these settings with a PRO or STUDIO plan: My Website / Design / Advanced / (click on the search component to edit its settings) / Style)
