How to move long text in headers to the next line on sidebar?

[Artur Dzhalilov]

Long headers of pages on left sidebar are not fully displayed its titles. They are displayed with ellipsis. To see the whole title I have to stretch the sidebar.

Confluence version 6.15.1.

How can I make the title of a long header automatically move to the next line?

Solve the problem by adding code: ".ia-fixed-sidebar div.plugin_pagetree ul.plugin_pagetree_children_list .plugin_pagetree_children_span a { white-space: normal; display: inline-block; }" into CSS Tables in Space tools.
