Enabling Search box in WordPress frontend template

Search box in wordpress is a widget. A widget is a PHP object that outputs some HTML. The same kind of widget can be used multiple times on the same page (e.g. the Text Widget). Widgets can save data in the database (in the options table).

When you create a new kind of widget, it will appear in the user’s Administration Screens at Appearance > Widgets.

A set of widgets is included with the default WordPress installation. In addition to these standard widgets, extra widgets can be included by themes or plugins. An advantage of widgets built into themes or plugins is to provide extra features and increase the number of widgets.
