I want to add (or restore, as appropriate) the vertical snap bar to allow the resizing of the metadata navigation pane on an on-premises SharePoint 2013 site.
This question was asked at least twice on StackExchange to resize the metadata navigation palette or here to resize-metadata-navigation-pane-using-code. The first point is Customize-keyfilter-and-treeview-navigation-bar-with-dragable-border-border which is unfortunately not available. Quoted on this page http://selingernetwork.com/blog/?p=78. I even found a page on this problem of configuration on Social Tech sharepoint-2013-customize-document-library-tree-navigation-bar
BUT I still can not make it work on our prod instance! I am not very competent with SharePoint being really new to it. I have a SharePoint designer that is a little out of date as I understand it but remains the default tool.
Should I specifically create a custom template to be used by a specific subsite, because I only see a template (how? Lost between seattle roles, v4 or oslo!). Is it possible to do this work at the library level? Is the script "NavResizer.js" recommended? (how else?)
Many questions, but the same topics! Thank you in advance.
