I have a from which will be displayed as multiple sections. when I reopen the form already selected values are unselected and only one values is selected. while partly this is issue in the server side. but I need help to understand how data is sent in payload from multiselect control.
for example : if I have selected 5 options in multiselect in payload I see all options as separate key value pairs where all keys are same.
sometimes I get all values in a comma separated value in a single key value pair.
It works if all values are passed as comma separated values.
attaching couple of screenshots for reference.
Let me know if any additional details is required.
If the MultiSelect component is placed inside a form, the selected values are sent as a key-value pair format and on the server side, the values will be received as an array. We have prepared a sample and shared it below for your reference.
