Restricting multiple components

[Kota Sreenivasa Shravana Kumar]

How do I restrict entering or selecting multiple component for a component field at the time of issue creating in JIRA for a particular project ?

Thanks

You don't.  The component field is multiple select.

You could use another field instead, or if you're willing to code, have another field and then pop the selection into components later.  Or try a Behaviour from the ScriptRunner add-on.
