Plumsail - Pre Select lookup multi select fields on Edit forms with few options

Forms SharePoint Online

I have a lookup field which displays a sharepoint list of items.
On New Form - if selected values, they are saved in multiline textbox.
Now on Edit form, I want this lookup list to pre select the values already selected.

Hi @humera.khan,

You can select values in a lookup by their IDs: Lookup field — Plumsail SharePoint Forms Documentation

This never works, It doesnot display the options selected already on the lookup list

Hi @humera.khan,

This doesn't work "out of the box", because the lookup field isn't the one storing the data. I suggest you loop through the lookup options with JavaScript on form render and enable the options mentioned in the text field. The article I linked details how you can work with the lookup field using code.
