Popup menu: Set a selected item on creation

Question

I have a popup_menu. I want to have the second, for example, option chosen when it opens, rather than the first.

Is this possible? I've looked in various threads on the internet and :help popup and found nothing. But I thought it would be worthwhile to ask here.

Answer 1

All of the popup creation functions return a window ID. So save the return value of popup_menu...

    let popid = popup_menu(...)

Then use that to reach into the popup buffer and move the cursor...

    call win_execute(popid, 'call cursor(2, 1)')

win_execute() is like execute() but operates in the context of a specified window.

This is mentioned at the end of :h popup-buffer.
