How To Add a Search Form

You can add a search form in two ways:

1
In an "HTML module", paste the code of a WordPress search form. For instance: 

<form role="search" action="/" id="searchform" method="get">   <label for="s">Search</label>  <input type="text" placeholder="Search &hellip;" id="s" value="" name="s"  size="50">   <input type="submit" value="Search" id="searchsubmit">  </form><br>

Using a "Widget module" where you can call the "Search form" widget from WP Admin > Appearance > Widgets.
