When you need to toggle between different views, consider using a tabnav. It'll give you a left-aligned horizontal row of... tabs!
<div class="tabnav"><nav class="tabnav-tabs" aria-label="Foo bar"><a class="tabnav-tab" href="#url" aria-current="page">Foo tab</a><a class="tabnav-tab" href="#url">Bar tab</a></nav></div>
Tabs can also contain icons and counters.

Use .float-right to align additional elements in the .tabnav:
<div class="tabnav"><a class="btn btn-sm float-right" href="#url" role="button">Button</a><nav class="tabnav-tabs" aria-label="Foo bar"><a class="tabnav-tab" href="#url" aria-current="page">Foo Tab</a><a class="tabnav-tab" href="#url">Bar Tab</a></nav></div>
Additional bits of text and links can be styled for optimal placement with .tabnav-extra:
<div class="tabnav"><div class="tabnav-extra float-right">Tabnav widget text here.</div><nav class="tabnav-tabs" aria-label="Foo bar"><a class="tabnav-tab" href="#url" aria-current="page">Foo Tab</a><a class="tabnav-tab" href="#url">Bar Tab</a></nav></div>
