About the drop-down 'categories' widget

Just open a random post on my blog.

Ex. : http://techtage.com/2013/03/concept-smartphone-with-customisable-hardware/

You can see the there’s a categories widget on the sidebar on the left. As the titles of a few categories are long, the drop-down menu is also very wide, as even long titles are shown in the same line of text. What I want is, a feature like max. characters # something, after which the rest of the title will appear below, in the next line, so the widget stays within the sidebar.

Any help would be gratefully appreciated.

Regards,
Rohit
