In this article I would like to take you through the 'Multiple Selections' possibility of Choice Columns, which is a less known feature.
Choice Field allows us to select an item from a set of multiple choices. For example, we are creating a choice field for Color & Choices Red, Green, Blue, and Yellow.
Create a new library & add anew column of type Choice.
You can see that the user can only select one of the values from drop-down.
Choice Field with Multiple Selections
Now we can enable multiple selections from a Choice Field. Open the list/library settings click the choice column & modify the 'Display choices' selection to 'Checkboxes'.
Now you can see the effect of change.
You can see that the drop down turned to be check boxes, thus enabling user to do multiple selection.
Metadata Term is also another way to associate multiple values to a column. In this case we have to configure Managed Metadata for the site.
In this article we have explored how to enabled Multiple Selection for a Choice Field. I hope this will help you in real world scenarios.
