WP_Customize_Control::render_content()

Render the control’s content.


Description Description

Allows the content to be overridden without having to rewrite the wrapper in $this::render().

Supports basic input types text, checkbox, textarea, radio, select and dropdown-pages. Additional input types such as email, url, number, hidden and date are supported implicitly.

Control content can alternately be rendered in JS. See WP_Customize_Control::print_template().
