Could you please help me with the following and an example or a sample code would be really helpful.
1. I have a drop down with three options (say option1, option2, option3) and when option1 selected, I need to populate a text box.
2. If the option1 is selected and if the user changes to other two options then text should be hidden or not visible to the user
3. Nothing should happen when option2 and options3 are selected.
Thanks in advance and appreciate all your help.
