Team,I am trying to create a manual dropdown field in an expression by the below syntax:
='<select> <option value="0"' selected="selected">Please select a name</option> <option value="1">One</option> <option value="2">Two</option></select>'

It is showing the dropdown while i test the rule, but it throws error when i use it in a process model. Please let me know where i went wrong here and suggest to correct the same?...
