How to avoid collapsing of breadcrumbs?

[Billiardist94]

Hi!
I'm using office-ui-fabric-react 5.135.6.
I try to implement Breadcrumb control on my form.

I want my navigation panel to look like this:

But, when I add this control on my page, the entire navigation panel collapses.


How can I avoid this behaviour? I don't want it to collapse.
