ReactUI: Suggestions for fill anchor for link to same page?

Hey,
have tried new reactUI and I’m very impressed. :ok_hand:

I would like to use the extended link-possibilities. I found the popup when double-click on the link. There is a dropDown for choose «anchor in same page».

But I can’t figure out, how I can fill the list for anchor for this page. Tried different but the output is always same like below: «No anchor for this page exists». (think would be the translation, can’t change the language, but this is an other topic :mask:)

##Question:

  • Does anybody has an Suggestion/Idea or a link to tut/doc how I could fill-up this empty list for anchors?
