Is there any way I can disable the creation of components on create screen? I want that components should be only added from the admin side and not from create screen
while Vikrant's advise is correct for the creation of new components I think you are referring to putting components into the corresponding field while creating/editing issues - is this correct?
If you do not want to have components added during create of an issue you can use an own screen for creating the issue.
With Admin side you probably mean to add components later, through Edit Screen?
If so, my above said applies.
Here is also a nice chart that explains the whole picture more easily:
