Drop down objects aren't capture by the recorder or by manual ..please give solution [v5.8.6]

Couldn’t select option from drop down list.

test case getting failed every time when it hit drop down.

Would need more information. Please share your script, there are many potential methods but we need to know what is failing. Typically you’ll want to id the drop down as an option then select option by label or index.
