How to add manually added value in selection column?

Question

I have a Sharepoint list with a "Select" option with "Can add values ​​manually."

How do I add a manually added value in the selection column so that it is available when adding and editing other entries?

Answer 1

I created a new list on my Office365 SharePoint site. When in manual mode, manually entered values ​​are not available when editing / creating new list items, regardless of which options are displayed in the drop-down menu, radio buttons or checkboxes with multiple selections. When switching from classic to modern SharePoint experience, manually entered values ​​are available when editing / adding list items. Hope this helps.
