User Problem

User would have an option to select checkbox type in custom field with drop down variant. Currently we have an option for checkbox type but without drop down. 

Steps to Reproduce

1. Click on card and navigate to Custom Field. 
2. Select the Custom field type as Checkbox 
3. We can see the Checkbox without drop down variant. 

Expected Results

User would be able to see the drop down variant. 

Workaround

As a workaround we can directly use Checklist and we add the items under the check list as a drop down variant.
