targeting option is not appearing on the modes dropdown on a page

check if you are able to see it on we-retail page?

http://localhost:4502/editor.html/content/we-retail/us/en.html

Go through this document - it sets up the page so this appears -- Working with Experience Fragments and the Experience Manager ContextHub

Add below in your headlibs

<!--/* Include Context Hub */-->

<sly data-sly-resource="${'contexthub' @ resourceType='granite/contexthub/components/contexthub'}"/>

yes it is seen on we-retail only, but i cannot see it on my own projects.

It is already there in my customheaderlibs file, although i remember one thing i did, which might have been wrong.

• On the Experience Manager rail, click or tap Tools > Sites > Context Hub.

• Click or tap the default Configuration Container.

• Click or tap the Context Hub Configuration.

• Click or tap the Create button, and then click or tap Context Hub UI Mode.

  But now when i am goint to tools- sites- contexthub, there is no default configuration container under global, it shows legacy configuration container and clicking on it shows me null.

  

yes thanks, i also tried this watching a video on the link Adobe Experience Manager Help | Set up ContextHub with AEM Sites , now I have got my targeting mode on the project's pages.

But after that the contextHub option on toolbar in the preview mode is not coming. Can i get help on that too?

Did you configure segments and audiences?
