Help please – hoping there's a plugin?!

Hi,

on my site I have a list of local classes on this page: https://www.findgodo.co.uk/kids-classes-watford/

I would like to organise it so that users could search somehow – could be a drop down list – could be click on a piece of text. I.e users could search by age group (and all the relevant classes appear) or by genre of class (all the same genre appear) or by business (all the classes run by that business appear).

Is there a plugin that can do this please or is there someway this can be achieved?
many thanks in advance. I’m still a novice so I won’t be able to do any coding etc!
