First thanks for using our theme and sorry the delay here!
Im usig Sydney Theme as a child theme. Elementor as a builder
When create a page and make it child page it doesn’t show child content on parent page.
I am little confused here, since child pages do not show their content inside the parent page. Can you explain with more details ?
Also Anchor do not work on header slider button and if I copy with Inspector section ID shows error.
How to fix it?
I saw you’ve defined the button link to #primary, but inspecting your website code we couldn’t find any section with the ID primary, and that’s the reason this is not working. Please try editing the page with Elementor and then, give the primary ID to the desired section you want the button scroll to:
I need when click on menu to go to specific part of any page so the options that have are to make child page or to have Anchor, but both do not work
You should create custom links for that, so you can define hashs/IDs to scroll until the desired section. For example, go to Appearance > Customize > Menus and create a custom link like the image below:
OBS: Make sure you have a section with the ID to scroll to (like I explained before).
We hope this helps!
Please try that and let us know if you need further assistance.
