How to make VSCode Intellisense window wider

Question

I have a VSCode extension that helps me autocomplete file paths, however many file paths grow long and are truncated in the VSCode intellisense popover window.

Answer 1

I don't think this is possible, VSCode generally gives extensions very little control over the built-in UI. See also the Restrictions section of the Extensions Capabilities Overview. Technically there is a way to hack around that, but I wouldn't necessarily recommend it.

There are also a number of settings for the suggest widget, but none of them seems to correspond directly to width. The closest you can get would be reducing the font size with "editor.suggestFontSize".
