So you say that you want to add only one item, even if you select multiple. Correct?

If yes, what is the foreach doing?

I really have a hard time following your explanation.

no if I select two values and if I click on addrowlink only one row should be available but I am getting 2 rows as shown in image. I want only one row even If I select multiple values in dropdown but in database the code should be updated for all selectedvalues

OK, but in line 7 you add one item for each selected insurer. If you only want to add a single item, foreach() will not make it.

then how to achieve it only one rowlink should be added and in backend the same value should be saved for multiple values and submit button is not available in this interface

1) how to achieve it only one rowlink should be added: Remove the foreach()

2) in backend the same value should be saved for multiple values: I do not know your data model. But some king of a one-to-many relationship might be an idea.

3) submit button is not available in this interface: Add a submit button. I do not know what you are doing or plan to achieve. The standard Appian way is the add an interface to a process start form, acquire the data in the form, submit it, and store the data using a write records node.
