yes, this is possible with the pro version (filtering on frontend), see details at https://mapsmarker.com/v2.7p for details

I read on your page that you can test the pro version for 28 days.
After this periode you still can use it but without any suport and updates.
But what happens when wordpress publish a new version and mapsmarker totaly do not work anymore??

And when I decide to take the pro version with updates and support after 3 months, is that possible?

HI Robert,
after the free 30 days trial period you will need a valid pro license to be able to continue using Maps Marker Pro. A purchased license is unexpiring and includes access to updates and support for 1, 2 or 3 years. After your access to updates and support has expired, you can still use the currently installed version of the plugin, but you will not be able to install new versions, unless you renew your access to updates and support for another year (at a discounted price).
if you have any more questions, let me know!
best,
Robert

OK I thought after the trial periode I still could use the pro version but without the updates and the ticket support.

I gonna think about it because perhaps as you regorniced I just start with the page. Ofcourse I hope people gonna visit and use it. When finaly nobody gonna use it then I bought the pro version for nothing.

OK, then maybe its a good idea to start testing the pro version after you launched your site and got the visitors/success you hoped for it. Good luck anyways!

Thankx
