Hello,
Unfortunately it is not possible to select multiple values in a dropdown control. However I have tried to use combo boxes to multi select options. Now I have come accross a problem that I cannot solve and I have wandered around the forums a lot lately.
In essence I am trying to make an advanced form which people can fill in and which is saved to a sharepoint list database. Patching single select dropdown controls have not been a problem for me with this type of syntax:
Country(Column name in SP list):{'@odata.type': "#Microsoft.Azure.Connectors.SharePoint.SPListExpandedReference",
Id:1,
Value:DrpCountry(dropdown control).Selected.Value}
However if I would for example ask to which countries someone has been in the last year I want them to pick multiple options. Combobox offers this multiple selection but if I try to use the patch syntax for this it won't create a new entry in the Sp list. It gives an unknown error.
Anyone got better ideas on how to patch multiple selections in a new entry on a sharepoint list? I would be glad to hear so.
