For a SharePoint online list I generated automatically the K2 Forms from SharePoint.
On this list I have a Lookup field that is pointing to another SharePoint online list with more than 3000 items.
On the generated forms for new/edit item, the control for this Lookup field is a multi-select, but it shows only the first 100 items.
It is possible to display all the items on the multi-select control?
Or there is a better solution to avoid the load of more than 3000 items?
