Tooltips in the side menu of the page tree for long page names. Edited

[Дмитрий Пересекин]

Hello!
The page names contain a lot of text and the page name does not completely fit in the page tree (even if the side menu is fully expanded). Is it possible to make it so that when you hover the cursor over the name of the page in the tree of pages, a window appears where the full name of the page will be displayed (by the principle of a hint) Tell me, is it possible to do this or is there an alternative solution for implementation? Roughly depicted on a screenshot.

CSS code would be fine, but when applied in space, the page tree is duplicated at the top of the screen. Is it possible to eliminate this and leave the text wrapping on a new line. Can anyone suggest the correct code?

.ia-fixed-sidebar div.plugin_pagetree ul.plugin_pagetree_children_list .plugin_pagetree_children_span a {    white-space:normal !important; }

Works only when applying global styles

Although such an alternative option is suitable, is it possible to implement the display of a window with a hint when hovering over the cursor using standard Confluence tools, or is it a separate development?
