Hi Kumarappan,
Where exactly you want to display the boolean attribute, if its workflow, OOTB boolean comes as a check box, but is its an attribute to be shown while creating the object in a wizard, you will have to write a data utility and render the attribute as a check box component. You will have to assign data utility ID in the type and attribute manager against that attribute for the object which is being created.
Please let me know if you need help in writing the data utility.
Thanks,
Aditya
