Error message should display if user select more than 5 options from multi select drop down Field

Question

Hello Community,

We have multi select drop down custom field which has more than 10 values inside it.

When user selects more than 6 values then it should throw the error instantly saying that "you cant select more than 6 values"

We can achieve this using JMEW validators. but validators works only when we do the transition.

But, We want to display the error message As soon as user selects more than 6 options.

We don't want to wait until user do the transition then showing the error message.

Thanks for the answer.

Yes, you are right, I have also reviewed and found out, that it is possible only in transition.

Thanks for the Reply.

The code is not working in Jira cloud. Also i found that real time field validation is not possible. we can get error only doing transition.

Hi @PLaksh11

If you have ScriptRunner, you can achieve this by using Behaviours in ScriptRunner.

If you have that:

Go To: ScriptRunner --> Behaviours
Create a new behavior and map it to your project + issuetype
Add the following script.

def field = getFieldByName("Your Multi-Select Field")
def selectedValues = field.getValue() as List

if (selectedValues?.size() > 6) {
field.setError("You can't select more than 6 values.")
} else {
field.clearError()
}

Let me know if you succeed.
