Current behavior
If you select options which have a property "value" they are not marked as checked.

this.cities = [
      { name: "New York", value: "NY" },
      { name: "Rome", value: "RM" },
      { name: "London", value: "LDN" },
      { name: "Istanbul", value: "IST" },
      { name: "Paris", value: "PRS" }
    ];

Seconded, I have to change my SelectItems to a custom {mylabel:string;myvalue:string} with multi-select option optionLabel="mylabel". The filter function returns the value in a format option1,option2 when using selectitem in multiselect

Hi, same issue for me. I am using multiselect with table for filtering a single column. The filtering works but the checkboxes are not shown as selected.

I am using optionalLabel = "name" and optionValue="myVal"

The object interface looks like:
{ name: string; myVal: el.string}

I have tried combinations of adding label and value keys to the object and removing optionLabel and optionValue from the html and no combination works entirely.

I have however noticed:

1. Setting optionValue or placing a value key in the object results in the filter working but the checkboxes not showing
2. Removing optionValue and removing a value key in the object results in the checkboxes showing but the filter not working.

Thank you for your time!
