[BUG] Unable to add extra text/component in people picker dropdown.

[ridhi58]

I am trying to use people picker component in my project.

However i want to include some extra texts/select all button on the top of the list as shown in the image below. but i do not see any template for that.

Also , is it possible to have checkboxes for multiselect . i see it is single select by default.

I tried going through documentation as well for all these things but couldnt find it.
