UI resize problems with long list of categories

[mgmax]

Too deeply nested long category names will break the GUI layout, as the window resizes too wide. The right or left end of the list should rather be clipped.
(example: Elektromaterial / Steckverbinder / Flachbandkabel / Kabel 10pin / ...)

I would opt for cutting off the front/left ("Elektromaterial" in the given example), because the latter contains very detailed information necessary to interpret the product names.

I would opt for that too.
When you are down in a detailed part of the tree, you probably want to search similar categories and therefore need the detailed breadcrumbs. Going back is also easy since clicking on the leftmost breadcrumb would ideally allow the UI to resize.
