Foldable, is also in some sense irremovable/unremovable (spell check objects) where as I think 'fixed' is a better description as it implies not foldable, removeable nor lowerable.

I was starting to write a whole page why I don't like "fixed" instead of
"unremovable" but the more I think about this, the more I like the value
"fixed".
One thing I worried about were flexible/soft bollards [0]. I would not
describe them as "fixed" regarding their ability to
move/bend/rotate/..., but they still remain on their location on the
ground, even though they are flexible. Therefore this would make sense
to call them "fixed".</pre>

<pre>Or call them what they are 'flexible'. No reason not to say what they are. </pre>

I currently don't know that a "lowerable" bollard looks like and how it
works. Do you have an example?</pre>

<pre>Can be found in my area .. though I cannot recall mapping them. They look the same as fixed ones ... The ones here are a simple tube shape , with an annulus at the base. Someone presses a button some wher and they slowly lower into the ground. And then I suppose another button is pressed and they slowly raise up.

<pre>Arr here is a supplier.</pre>

<pre>They call them 'retractable' - various ones - air operated, key or padlock.</pre>
<pre>I am certain there will be other suppliers.

I would love to hear some feedback on these two values:
"fixed":
A bollard which cannot be removed without destroying it or at least
cause severe damage to it. If a bollard has some sort of lock to remove
it, it's *not* fixed.
"foldable":
A bollard which can be rotated so it lays on the ground so that e.g.
vehicles can pass it [1]. Some kind of key or wrench might be needed.
This bollard can easily be moved back to it's previous position with no
damage left.
