To display a custom field based on another drop down custom field value

[Amrik Birdi]

Hello,

I have a custom drop down single select field called CTF which has values of 'Created', 'Updated' & 'N/A'.

I also have the following multi line custom fields; 'CFT - Created', 'CFT - Updated' & 'CFT - N/A'.

What I would to see is the following:

If I was to select Created from the drop down I would like to see CFT - Created' (multi line field) only and the both the 'CFT - Updated' & 'CFT - N/A'. multi lines must not be visible

If I was to select Updated from the drop down I would like to see CFT - Updated' (multi line field) and the both the 'CFT - Created' & 'CFT - N/A'. multi lines must not be visible

and finally if I was to select N/A from the drop down I would like to see CFT - N/A' (multi line field) only and the both the 'CFT - Created' & 'CFT - Updated'. multi lines must not be visible

We have Scriptrunner and I have been looking at Behaviours but this is not my strong point. Can anyone help?

regards

Amrik
