XF 2.2 Possible to limit the amount of items selected in an autocomplete

[Grant]

Hello

I'm using the code used for finding tags, elsewhere on the site:

<xf:tokeninputrow name="tags" value="{$tags}" href="{{ link('misc/tag-auto-complete') }}"
                label="{{ phrase('tags') }}" />

At the moment it allows you to select a seemingly infinite amount of tags:



Is there away of limiting it to one

I've tried ac="single", which I've seen elsewhere.

Thanks in advance

Found the answer, - just need to add

max-tokens="1"
