jsx-wrap-multilines ​

Disallow missing parentheses around multiline JSX.

Wrapping multiline JSX in parentheses can improve readability and/or convenience.

Rule Details ​

This rule optionally takes a second parameter in the form of an object, containing places to apply the rule. By default, all the syntax listed below will be checked except the conditions out of declaration or assignment, logical expressions and JSX attributes, but these can be explicitly disabled. Any syntax type missing in the object will follow the default behavior displayed below.
