How to create a drop down that has the text of link selected in it?

Hi Friends. Can someone share how I can create a drop down menu like this? (screen recording added)

Screen Recording - Dropbox - Screen Recording 2022-10-27 at 11.25.32 - Simplify your life

The native web-flow dropdown does not change the dropdown’s toggle text to the link’s text that I select in the dropdown. That is what I want to achieve. (If I select Introduction, The toggle text should also change and so on…)

Please help me with your thoughts. TIA.

PS: I haven’t start creating this one yet. So I don’t have a read only link yet.
