How to show or hide GP widget on specific pages?

Hi there,

For sidebar widgets? If so I would recommend this handy plugin:
https://en-ca.wordpress.org/plugins/content-aware-sidebars/

If not then we need to use some CSS. Can you link me to the page and let me know which widgets you would like to hide?

Hi, let say I want to have the search field ( in header ) only on specific pages.

Ok so use Tom's Simple CSS plugin: https://docs.generatepress.com/article/adding-css/#simple-css

and add this CSS in the CSS meta box on the pages you don't want the search field:

.header-widget {
    display: none;
}

Index pages (blog, archive) need to be handle differently so let me know if you want to hide it on them too.
