Customizing header section

Hi Tom it have inside GP Hooks but the content should be managed by an editor user via GUI of WordPress no writting html code directly.

Exists a plugin or extension? I don't know how can do that...

Hmm, that would involve some custom coding, as you would need to create a TinyMCE editor option in the Dashboard. It's likely much easier to just build your content from within a page using the editor, then copy the HTML generated by the editor and paste it into GP Hooks.

Hi again, i have another question... Is possible add a countdown clock to the header section? And if it's possible how i can do that?

Thank you!

Perhaps a plugin? https://wpdean.com/wordpress-countdown-timer-plugins/

Thank you for answer me a plugin an option any solution is acceptable but how can put this plugin into header layout of GP?

Depends where you want to insert it and how they provide the code.

Header widget might be an option?

Let me know.

I want insert it just below of the menu bar and i guess it's possible use a widget but i don't know how...

Maybe try the After Header hook?

If the plugin is in widget form then try this plugin:
https://en-ca.wordpress.org/plugins/widget-shortcode/

But how add a countdown clock to a hook?
I have elementor pro too, I don't know if can use it for that?

Depends on the plugin you are choosing? Is it in widget form or shortcode etc?

i want a countdown clock never mind if a shortcode or a widget

Which plugin are you using and how do they want you to insert it?

I haven't a plugin yet maybe can use the countdown of elementor i don't know im new in this part

Accept recomendations

I've never used one myself either unfortunately.
But if Elementor has it then it might not be a bad idea since you are already using it?

Actually I'm using elementor pro but I don't know how i can include it into header layout of th GP theme

What is the way to do that?
