For multiple selection you can use Checklist or List with Multiple Selection. You cannot do a multiple selection using a drop down box.

Unfortunately no, not without doing something custom via some code.  Having a drop down checkbox option would be a great feature that I've wished was available several times in the past.   In fact you've inspired me to post the idea on User Voice - so  lets hope it gets some attention so Nintex implements it! Vote  it up at the following link:

Multi-select Drop Down – Customer Feedback for Nintex 

Hi Ryan,

The option for Checklist or List is not available with me either on SharePoint or in Nintex Form.  In SharePoint I get options only

DropDown

Radio Button

Chekboxes (for multiple selection)

If I use Checkboxes then all 25 choices will be shown on the form.  So option remain with me is only DropDown.

Thanks for the reply.

What version of Nintex are you on?

It looks like 2010

http://help.nintex.com/en-us/nintex2010/help/#Forms/RootCategory/Controls/Nintex.Forms.Controls.Choice.htm%3FTocPath%3DN… 

List should be available to you in that version as with all versions I think.

Hi Ryan,

Thanks for your support and useful tips.

We have Nintex 2010.

I tried Choice option by selecting from General Control and it gives option of List.  However, when I tried to assign list variable to "Connect to" the option disappear.  Please refer below two screen shots:

1.  Before assigning value to "Connect to"

2.  Screen shot after assigning value to "Connect to".  test is a List column.  The Choice option is not available if "Connect to" value assigned.

What data type is your "test" column?

test column is Choice data type.

Ah right, I see. So when the control is connected to the choice column it will behave however set out by the SharePoint column. However, if you connect the control up to a single line of text column then you'll have full control over the...er...control!

Yes, connect to single line of text works.  Now I am getting multiple selection items as below :

abcd;#efghijk;#ybxlld

Is there any way to get items as : abcd;efghijk;ybxlld

or in multiple lines like

        abcd

        efghijk

         ybxlld

Cheers:)

You can use the parseLookup runtime function for that. 

I tried giving parseLookup runtime function in Form Variable, but it does not give desired result. the form variable setup is as below.  Please help.

Product Name_SL contains vlaues as : abcd;#ekdkd;#jkfkfjkf;

and need value in Product Name_ML as :

abcd

ekdkd

jkfkfjkf

Hey Ryan,

For the past two days, the same kind of issue is bothering me, I found your solution very useful. 

Thanks and Regards
