Null/empty value for drop down list

[Former Member]

Hi,

Iu2019m using Drop down List and I'd like to have the first entry as "Empty" automatically be selected the first time that the interactive form is opened. Iu2019m using ISR DDL 1st Element preselect for Drop down list and values are populating dynamically into the drop down list.

Problem Iu2019m having in adding empty value into the drop down list.

Is there any setting for "empty" value, can we change empty to "unknownu201D.

Can anyone help me?

hi vergeseMatz,

As per my knowledge this can be done.

"Is it possible to keep the options in the drop down list when we click the button to filter ?"

Just call the Bapi/Data service which is giving the searched values after the filter button event is triggered.And mentioned that Bapi/data service in the dynamic property of the Drop down list.Do not forget to assign that link with the value selceted before the filter button is clicked.

"clear the drop down list values when we click the button to reset?"

you have to perform the same action but while reseting just send a blank or null value for search to Bapi/data service. Then do the same mentioned above.Since there will be no input for the search bapi/data service so no values will be populated in drop down.

I hope it will help you.

Thanks and Regards,
