In a UI15 environment, the width of the Navigator frame can be adjusted by simply dragging the edge to the desired size. Environment Instances with the UI16 interface Cause In UI16 the width of the ‘navpage-nav’ element of the Navigator is hard coded within the ‘css_includes_concourse.cssx’ file to be 285 pixels. .navpage-nav { width: 285px; position: absolute; top: 50px; right: auto; bottom: 0; left: 0; transition: 400ms cubic-bezier(0.645, 0.045, 0.355, 1); } Resolution As a workaround, you should look to use concise naming conventions for Application, Module, and Page names that appear within the Navigator.
