How to change the width of NormalPeoplePicker dropdown - office-ui-fabric

Question

I'm using default example of NormalPeoplePicker from https://developer.microsoft.com/en-us/fluentui#/controls/web/peoplepicker#IPeoplePickerProps.
When the dropdown displays it cuts off longer items (example: 'Anny Lundqvist, Junior Manager of Soft..'). How do I make it wider, so that the full item's text displays?

Answer 1

Component which renders suggestion list have fixed width of 180px. Take a look at PeoplePickerItemSuggestion.styles.ts.
What you can do is to modify this class .ms-PeoplePicker-Persona:
.ms-PeoplePicker-Persona {
width: 260px; // Or what ever you want
}
UPDATE - Solution from comments
Change width trough styles property of PeoplePickerItemSuggestion Component
const onRenderSuggestionsItem = (personaProps, suggestionsProps) => (
<PeoplePickerItemSuggestion
personaProps={personaProps}
suggestionsProps={suggestionsProps}
styles={{ personaWrapper: { width: '100%' }}}
/>
);
<NormalPeoplePicker
onRenderSuggestionsItem={onRenderSuggestionsItem}
pickerCalloutProps={{ calloutWidth: 500 }}
...restProps
/>
