Kadence has great search settings, which allow you to control how readers search and interact with content on your website. Here’s a guide on how you can customize search settings using Kadence:
Go to Appearance > Customize > Header to add the search bar in the header. You can add the Search widget anywhere in the header.

Drag the search widget to where you want it in the menu, and then click on the cog wheel ⚙️ to design it, including its style, color, background, border, and width.
You can also add a search toggle to your mobile settings. Switch to the Tablet/Mobile tab, then repeat the above.
NOTE: If some of these options are unavailable, you most likely do not have the Kadence Pro installed.
