Conditional Widgets
by Jason LeMahieu (MadtownLems) on WordPress.org
Each widget gets an expandable form at the bottom of it for controlling display options on the home page and for both pages and categories.
IMPORTANT: This plugin will NOT function after the Widgets screen overhaul that is part of WordPress 5.8 unless you use the Classic Widgets plugin (https://wordpress.org/plugins/classic-widgets/). The plugin will continue to be supported/maintained for those using Classic Widgets, but there are no plans to make Conditional Widgets work once Widgets are Blocks.
This plugin adds a form to each widget on the Widgets panel which allows users to choose which pages and/or categories the widget is either displayed on or hidden from.
For each widget, you can choose criteria to either SHOW or HIDE the widget, based on a number of categories. The interface is quite intuitive, and requires no knowledge of php or conditional tags.
